I added the dwarf (chain) to my tank loach snail problem. They are as small as a man rather than the National Front to push past him to eat fried, but large enough to eliminate the snails in about a half the problem...

I am far from an expert, but I have 3 240 gallon tank in a different boy. All 3 fish now live in the exact same piece of furniture. I think this will change as they grow, but now they are like the three Amigos, at the same time, they even share a piece of potato or zuchini...

I do not know from personal experience, but I must say, they are quite recently "released " - this probably refers to spawn two or two weeks before (or at least "common"birstlenose about two weeks of freedom When swimming, but it also depends on water temperature)
