i have 7 cories and 2 pictus cats and 4 tiger barbs in my 55g, would i be able to buy more tiger barbs? oh yeah, there is also a pleco in there too... he is like 5 inches long. i could move the pleco to my 125g if you think i should. and how big should i expect them to get? i read that they get to 2.5 inches.... and one more thing, how eays is it to breed them?
