actually, the sharks and cat fish were named, Psycho (bala), Savage (irid) and Kain (cat fish). psyco died cause he picked on the cat fish and the cat fish whoped him one too many times for it (sorry but that cat fish didnt take *beep* from no one!) and Savage went psycho when Psycho died and kept trying to commit suicide by not eating, but his hunger got the better of him. but kain died last, he was almost 2 months at my home, i TOLD my friends, but they wont tell me why their sharks arent hostile.
I can't help but say, you have no idea what you're doing. There is no way these fish were happy in that tank, or even remotely healthy. No way. Not at all, not a chance. They probably died due to health problems from stunted growth or poor water quality.
If you want big fish, you have to have a big tank. If you don't like small fish, you're just kinda out of luck until you have the money for a larger tank.
They weren't playing. They were fighting. The iridescent wasn't sad, it was sick. Their 'sharks' (Most of these aren't even true sharks, they are named such due to a similar shape and to get consumer's attention. Bala sharks are actually a large minnow) probably had a lot of space to establish territories in, and therefore did not have aggression issues.
Black sharks will kill just about anything they can. The word I know from a friend who kept them was if they can't fit their mouth around it to eat it, they'll ram and headbutt it until it dies.. Then eat it.
Danios are the fastest fish you'll find. After that are probably guppies, swordtails, and platys, for your normal range of available small fish. Then you get into Tetras.
Swordtails to my knowledge will have a few babies every 4-5 weeks. 12+ babies I believe, though they usually eat some of them and/or all of them
