severum mama is right. Unless you want to have an excuse for a bigger tank like me with 7 BP's, 4 angels, 10 neons, 9 Otto's, 3 Cory and 2 Silver Dollars in a 120 tank, you should stop where your at. Mine took a month to come out of hiding but it did help to associated my self with feeding time. Now I cant hold them back and they are constantly digging now but the plastic pots used as caves really helped settle them. Now Im adding a 2nd canister filter very soon so its established for my next tank a 150 minimum but I wish for a 300. I found one with a stand and all equipment for $1000 but my goodness how will I get it home.
