Ok, so i have a 40g with 2 ocelaris about 3" right now. i am about to order some monos and orinos (i wanted to get 4 of each). Soon i will be changing my 125g (72x18x24) into a grow out for my Pbass. I was thinking i could raise 10 - 12 in there to about 10"-12" with an FX5 and AC110 filtering it. Eventually my favorite pair(s) will be moved to my 240g. But first i wanted to get some input from the pros before i moved forward with my project. Also i was curious what you guys think the best substrate is for them? I was going to go with small smooth pebbles with speratic larger flat and smooth stones.
