I've recently used some to glue pieces back onto my overflow after small fish kept tumbling down into my sump and it seemed ok but i recently covered it over with silicone just in case. But I didn't experience anything unusual if that helps..
I've never seen them before but I have heard about how they are dye injected. try googling them or if you can speak to the people in the store however I wouldn't expect them to know or exactly tell the truth. But that's just my opinion
There is an add on kijiji right now selling brackish water fish check it out maybe some of them interest you. This is what was available
1 Green Scat $40
1 Dragon Goby $30
2 Knight Goby $15 each
1 BumbleBee Goby $10
cheers
Yup that's them alright.... Long gone are the days when they were 10 bucks at PJ's. I haven't had them in years, voracious eaters for sure. Almost makes me want one again..
Nice Pics !!
Well I think I'd buy one just to say I got one. Besides it's always a good excuse to buy larger and larger tanks aside from the 300 i already own...
So if you can do it then i say go for it. not much different than arowanas really.
