No Angels in the tank, He wants Tiger Barbs! Mom does not want them because I heard of bad and good. He does not want gold barbs and other cherry barbs because sister has her own tank. We must be different!!!!! I went on the Tetra plan, but we still like those fast moving tigers! What Tetras work with Tigers? He does not care for danios. We have read and looked for Months, the tank is waiting. It is doing the fishless cycle. What to eat the green on the sides of the tank? Need something small, no otto with Barbs, Correct! I read serpaes are nippy, good match with Tigers? Mom gone nuts!!!!!!!!
