Genetics... Biology 30. Albinism is an absence of pigmentation is due to recessive genes or a simple mutation. The mutation, by definition, is genetically unpredictable. But there is some predictability to genetic pairing. You can use a punnett square to plot the theoretical possibilities. Albino is always recessive so an albino animal is a homozygous albino (aa) genotype. Your phenotype calico can be a homozygous (CC) or heterozygous (Ca) genotype. 1. CC + aa = Ca, Ca, Ca, Ca (all hetrozygous calicos, no albinos) 2. Ca + aa = Ca, Ca, aa, aa (het and albino are possible) All theoretical predictions. You could have a hetrozygous calico parent (Ca) and not see albino offspring. But pairing your calico with an albino is the only way you will learn what genotype your calico is; hetrozygous (Ca) or homozygous (CC). Add fin traits to the mix and you jump from 4 theoretical combinations to 16.

Thanks for the thread on Levamisole HCL dosing Jayba! One of the links you shared contains an article on loaches.com written by Shari Sanford, although her bibliography link wasn't working the last time I tried. Shari mentions that inverts can be part of the callamanus life cycle. She also mentions an alternative treatment called Flubendazole, which she says, "will kill snails." I compared this to Diflubenzuron that appears on the ingredient list for Jungle Parasite Clear (yes, I got unlazy). JPC advises against using the chemical with crabs or shrimp. Hmm. As expected, there are plenty of web opinions about whether or not these are the same chem, but I couldn't find a single web fact positively linking the two. However, I did find both chemicals listed on aquafolie.com under the collective warning "Do not use with invertebrates" (all in French though). It makes for a strong case to deworm during QT (imo). After that... Do you have inverts with your bettas Nanmer? Edit: mispelled French

Ok. I read that VHO=T12 before, now that you mention it. But I checked out when I saw T12. I'm paying attention now. I've heard/read people using PC and CFL (2G11) interchangeably... and CFL, referring to the little spiral fluorescents that screw into incandescent sockets. Sometimes the colloquial use of the terms makes them enigmatic. Thankfully, that hasn't happened to toilet paper. The fixture is really light weight; it has a ~22ga wire on both sides of the frame that slide out to suspend the fixture - I reckon my Hagen Glos are ~12ga. I assume I'll have to rip the fixture apart to change the tombstones anyways. How will I know if the ballast is electronic? Is weight any indication? BTW: I miss your other avatar jewels

just to clarify <---blind chicken

Levamisole HCL came to mind right away. Does anyone know what distinguishes JPC from levamisole? Edit: Yes, I'm too lazy to look

Thanks for the encouragement. Reading this might feel a lot like chewing tinfoil, but this is the second time these eggs showed up. On March 2, three weeks after I got them home, there were 4 eggs in there that I could see. 5 days later - gone. I was kicking t-rds down the road for not having a spare tank to put them in -and- I was too embarassed to go public. I certainly didn't expect to see these either - just about peed myself running down the stairs, got cheesed when I realized I still didn't have a spare tank ready to go... sigh. The scene here this afternoon was alot like keystone cops. And I was thinking about you Jay, grinning the whole time. I'm counting 16 eggs; 6 are stuck to the suction tube just above the inlet screen. And it's raining apple snails ta boot! Don't be too envious Jason. Even a blind chicken can find a kernal of corn. I'll be in touch Steve. And I'll keep everyone posted.

This isn't so much a question about fry as it is sharing my tank dwellers' victory. After watching about 8 apple clutches of various sizes and locations, I came home to find my tank glass sprinkled with little white snails. Looking closer, I also spied little spheres that didn’t look so snail-like. These two photos are for you Jayba. I am in the process of rounding up a small tank to transfer the eggs to. edit: snail photos removed

Seems I'm suffering the ill effects of my 15 year hiatus. I picked up an older Coralife dual fixture that I reckoned was T5HO. But it's a 1/2" shorter than a T5 tube. The socket looks like it takes a small square nib over against two pins. Ring a bell with the sw community?

auction? what auction?

The account of my experience isn't an opinion.

Being a great ambassador means fairly representing a product without being condescending, evasive or misleading to a potential customer. Demonstrating any of those qualities is short-sighted and harms a person's credibility. ...to distinguish between possibility and probability. Thanks to the internet, people can read about the MSDS change, read people's opinions about the same, and decide for themselves if that discredits Seachem or their Purigen product. "I dropped emails to Seachem and Eheim to answer specific concerns. Responses from both companies were direct and forthcoming." They told me what I could and should not expect, and based on that information, I was able to make my own educated assessment. I've not been disappointed.

sniffle. I wanted to go...

:welcome: Be welcomed!

Plug Purigen in the search field here and you'll find informative member feedback on this product. I found those threads very helpful. I also dropped emails to Seachem and Eheim to answer specific concerns. Responses from both companies were direct and forthcoming; great ambassadors who knew their respective products (and each other's).

eloquently put - and more direct than my suggestion. As long as the one preparing the fish for export is even aware Jorg. A thorough inspector might raise a brow at bag bearing a named Brazilian species coming out of Peru. But label them as Peru (w/o nomenclature), and the inspector would have to positively identify them and their origin (maybe on Planet Catfish). Speculation on my part; I know nuthing... I didn't even get up this morning. Please pass the cory catsup.

Maybe Peru was an inductive guess.

you got it bad dood!

I wondered about P. assimilis but I didn't note it having such an obvious subterminal mouth position. I regret not taking my own photo; a flank shot would help.

TDS is positively correlated to brown algae (diatom), but it's not always causal. TDS does influence ph. So it'd be wise to locate the cause of your TDS swing. Discover and treat the cause and you eliminate its symptoms. Brilliant! A great way to isolate and evaluate your substrate! edit: sp

I went to look at some hard goods and saw this fish. The black spot is oval shaped, poor tail tip color, fast swimmer ~5" long. This fish is one of 4 tank mates; one of which looks like a single M. boesemani (which is also has poor color). What say you?

It's "cabomba bomba hornworticus rex". A new plant recently imported from Neale Lake, just NE of Lloyd. jk I really like how your plants are growing around your driftwood. Well done!

I'm wondering about your substrate. What kind of substrate is shrimp substrate? Is it from your previous tank? If so, maybe it was deteriorating in the lower strata... pouring it over to a new tank, is now exposed to water and dissolving. Just a guess. Edit: Were you using a product like aquasoil?

in other words, fluids travel the path of least resistance. Nice splitter in the link. If you have one supply line feeding two delivery lines and the flow to each will be the same (all the time) a pneumatic shuttle valve (flow divider) is a good tool. But I'm dropping into the middle of a conversation so I may not be picturing your arrangement rightly.
