i understand i should use a bigger tank, but its what i got for a short time, and i dont remember what exactly the 4 i have in there so far are called. But there nothing to extravagant, i got them for like 12.99 at petsmart, 2 are yellow with black stripes, 1 is bright orange, and the other is a lil harder to discribe, cause it doesnt really get its color tell its older. And i heard its better to slightly overstock with ACs, to better distribute aggression. If that is true i would like to get 3 more, 2 jewls, and one that was blue with a black stripe. Any advice would be greatly appreciated, this being my first african tank.
