I have a new 30 gallon tank cycling with two zebra danios in it right now. My plan is to have a small school (at least six) tiger barbs in it. my question is, how many fish can i keep safetly in a tank that size. Ideally, what I want is 6-7 tigers, the 2 danios currently residing, and one bottom feeder OR algae eater (pleco or a red tailed shark). Is that too high of a load for a 30 gallon?? the barbs are a must, cause I already have three in a smaller tank, and they will agress on my danios if i don't have enough. i really want the benefits of a scavenger like a pleco or shark- but if i will be pushing the limits of my tank, then i won't do it. it is a moderately planted tank, if that helps.
Also- my 10 gallon will be vacant once I move my barbs over, I was thinking of keeping mollies or guppies, hwo many can I keep in a 10 gallon tank? or is there a fish that prefers a solitary life (other than a beta)??
