I had 3 of mine doing this about a month ago and within days they were all dead.. I hope somebody can help you out. Oh nooo D: I'm sorry about your fish. I've been noticing them doing this for the past two months. They gulp for a few seconds then zip back down to swim around. Hopefully they'll be okay.

I have four angels in my 75 gallon planted (along with various other fishes). From time to time they swim up to the surface and gasp or gulp. Its only the angelfish that appear to be affected, none of the other fish are doing this. Their breathing rate appears to be otherwise normal when they're swimming around the tank. They look healthy. No stringy white poop, no behaviour abnormalities (apart from the gulping). My ammonia and nitrite are 0. Nitrate is >50mg/L but <110mg/L. Is this possibly due to high nitrates? Ideas?

So it turns out that despite the potential problems with cloning the mamoth there are actually three competing groups of scientists who are actually going to give it a go (including the fellow who cloned the first dog).

I hear tiger fish tend to waste away in captivity. You should post some pictures of the lun and his/her teeth plates.

"Glow in the dark" is a misnomer. What is probably happening it fluroescence which is when a compund absorbs light of a particular wavelength (generally a shorter wavelength and therefore higher energy) which excites electrons causing them to jump to a higher energy level. These electrons eventually fall back down to their original energy level releasing energy in the form of photons of a lower energy (longer wavelength). So a light of a particular wavelength must first be shon on the fish/animal/structure in question for the flourescence to occur. They wouldn't "glow" in complete darkness. They certainly could have been genetically manipulated (sadly as Jvision pointed out its also possible that they have been injected as adults with a dye. This would be a lot cheaper.) In Science, Green Fluorescent Protein (originally isolated from jellyfish) is used for the visualization of gene expression. Basically you take the sequence GFP and you insert it into a gene (the actual process is obvious a bit more complicated than this, especially if you start from scratch) so that you can see how that gene works. It gives pretty pictures like these: http://ars.sciencedi...4008267-gr3.jpg When done in zebrafish, the embryos are often photographed because they're see through. The University has ~9000 zebrafish some of which have been engineered in similiar ways for different purposes (all justified exhaustively to ethics board). They also have some cool things like the casper strain zebrafish: http://images.caroli...l/155590_lo.jpg Which will probably never be avaible commercially. If it does become avaible commercially it means that some academic is going to loose all their grants and torn down by their home universities ethics commitee. Those angels have probably had GFP inserted in a gene involved in pigment/scale/irrophore (Numerous possibilities) deposition. This is ofcourse assuming they weren't just injected with a dye. As we all know the Canadian government has decided that using molecular techniques to create aquarium strain fish is unethical and has made it illegal to sell said fish. One of their concerns is that people will loose appreciation for the way natural fish look. Of course we all know it can have the opposite effect on some of us and make us only want wild type fish (I say wild type NOT wild caught). It shouldn't matter to you guys if they come directly from the wild so long as they look like their wild relatives. Taking fish from the wild can be extremely detrimental to the environmental (Rosaline sharks/Indian flasher barbs are now rather scarce in the wild). On the other hand, breeding fancy strains of fish achieve the same ends just much much slower. Flowerhorns are a good example. There are a few roadblocks to bringing back the whooly mammoth: 1) We have sequenced most of their genomes but this has been done from select few individuals and could be full of all sorts of deleterious mutations. 2) Their Y chromosome hasn't been sequenced (even in elephants). So they'd all be female. 3) The mammoth embryo would have to be implanted into a female elephant. This may or may not work, very high chance it would be rejected. No one is really sure. There are some other issues but these are what I can remember off the top of my head.

I have also been told that if you don't prune the flowering stalks of Aponogeton that main body of the plant will die.

Congrats! Galaxies rasboras if we are talking about the same fish are actually a member of the Danio genus and is indeed an egg scatterer. Good lucking hatching/raising them (should be pretty easy)!

The name giant danio is misleading. Zebra danios which is likely what you have are Danio rerio, however Giant danios are Dario aequipinnatus. Different genus, a closely related but different none the less. Most fish won't shoal with other species (not always true, or would prefer their own species), corrydora catfish are a good example, all those different coloured and patterned corries are actually different species. Corries only want to school with corries of the same species. The pictus would very likely eat the danios once they can fit the danios in their mouth. The corries will be fine as they have poison barbs that will discourage the pictus. The glass cats would probably be fine, the activity level of the pictus might stress them out. The pictus will also take up a pretty good chunk of the space in your tank, so you'll be limiting the number of other fish you can keep. This site is a good benchmark (its not the say all and end all): http://aqadvisor.com/ Pufferfish, even the south americans, are a wild card. They're likely at the least to nip fins and I wouldn't keep it with any small fish. Also keep in minf you'll have to feed them snails to keep their beaks from over growing.

Found this article pointing out 21 species of land plants commonly sold as a aquatics. I've definitely seen a few of them around Edmonton sold as such (not going to name names). Also provides some tips for telling if plants are aquatic. The technicallity here is that many aquatic plants can be grown out of water as well. This is explained as well. http://www.practicalfishkeeping.co.uk/content.php?sid=4741

I have yet to be able to get my plants to sweat T_T (That's what I get for not using substrate ferts).

Its...adorable. You don't have any problems meeting the oxygen requirements of these guys in a planted tank (assuming you have little surface turbulence that is).

More "exotic" danio species would actually be pretty cool.

Awesome, you appear to be spot on. Though the mouth pictures on planet catfish look a some what different. At the very least its the same genus. Got him at Big Als here in Edmonton. Lovely fish when he comes out, the only one in the tank who'll case my flying fox.

He was sold to me as a bruno pleco but I don't think that's what he is.

Right makes sense. True eels move between salt and fresh at two points of their life cycle for breeding. They're a Catadromous fish meaning the live in fresh waters as adults and move to salt to breed. Cool thing about eels is that they have this life stage called Leptocephalus larvae. Looks nothing like an eel, compressed see-through ribbon-like things which metamophose (weird thing is they actually get smaller when this happens) into what we commonly call eels. There are a whole bunch of leptocephalus larvae that are not known which species of eel (or tarpon a closely related group that also does this) they belong too. No one has ever seen eels breed in the wild either. Visual aid: http://www.mnr.gov.on.ca/stdprodconsume/groups/lr/@mnr/@sorr/documents/images/mnr_e003649.jpg They're quite mysterious. So many many fish to study and not enough Scientists/grant money/time.

Fresh or Salt water eels? Fresh: I have seen various spiny eels at both Big Als and Aquarium Central. Now technically spiny eels are not true eels as they are not an Anguillid. However most spiny eels stay relatively small so its a good place to start and look like eels to the untrained eye. Spiny eels include -> Fire, tire-track and zig-zag eels (all being Mastacembelids I believe?) Are Anguilloids ever actually sold for Fresh water? I'm not sure, does anyone know? Salt: (This is where you're more likely to see true eels) Pretty sure Big Als carries salt water eels and some of them are probably true eels. In terms of learning about eel care. Independent research is generally the best. Be sure to check multiple sources to verify the presented information These guys are a decent place to start: http://www.wetwebmedia.com/

If it is in fact illegal, don't do it. There are fish-cops, for real.

Very very cool. I do believe most piranha breed during the wet season when everything floods, so its likely that with an increase in water depth a decrease in light would accompany it. What species are they?

Oh noo. Your poor fish ): This is what I have nightmares about. If my 75 gallon were to ever give out, ooh I don't want to think about it.

Has anyone even heard of the brand?

That's horrific D: I shudder to think what this person's idea of an "extra large filter" is.

I've read that Flying Foxes can be aggressive towards some species of loaches since they can be similar in body form to Flying foxes. Anybody know if Khuli loaches would be compatable with my flying fox(he's about 4inches at the moment)?

Fish can get cataracts to. However I have actually seen betta's flare at other species. I knew a guy with a old man betta who'd flare and chase the rams (well pretty much any of the fish tat came to near him) in his planted tank.

Water aspirators are all well and good. They just use sooo much water, which is my main concern(in addition to the health of my fish).

Wouldn't not changing my water for a month be bad for my fish? Surely the plants and my bacteria can't keep the ammonia in check for a month.
