Pufferpunk, as to what happened to the Black Shark, it was in the tank for three days and early this morning was found to have a fungus of some sort on it's throat, mouth and face, including one of it's eyes. It was swimming upside down, so we dosed the tank with meds, but didn't seem to help much. Was a gradual downhill decline, eventually it died, so my brother flushed it. His betta (which he is yet to name) will be returned to my brothers tank once the meds have cleared up and there is no sign of the fungus returning. (And if I think it's ready to be put in)
And thank you AsaPW, for not grinding us into the dirt.
Also, to most other people, instead of just posting on this thread and telling us how you think our tank is overstocked, has supposedly incompatibale fish and making us feel like idiots, try maybe giving some advice to us, instead of pressing our buttons. Not meaning to sound harsh or rude or anything like that, just stating the fact some of you just seem to be critising us when I'm sure you haven't got absolutely perfect tanks.
We know we have large fish and a very odd assortment of them aswell, as we've been told by family members that we have the oddest collection some of them have ever known. But there is really only one way to find out for yourself if fish can go together or not. I experiment every now and then with my bettas, and sometimes do the same thing to the largest tank.
All fish that are in there now are healthy and happy, even more so when they get their tank infected with live daphnia, mosquito lava and blood worms
