The 110 is nearly ready. The tubes and the rockwork, the heaters and filter, the big hunk o' slate footed driftwood - these are all in place. Next up is mixing sand and organic potting soil and laying the substrate. The light is there, all 260 watts of it, and all I need to do now is cover the tank, plunk it down, and set up the timers. Then 2 dozen feeder guppies for cycling, and swords, vals, sags, lilies, and ferns and it'll be ready for the fish.
I have 3 bushfish (Ctenopoma acutirostre
) about 3 1/2" long in a 25 gallon earmarked for this tank. I am planning on getting another 3 (they'll be about an inch and a half when I get them), a couple off swordtails (a male and 3 females - X. helleri), and a pair of Senegal bichirs (Polypterus senegalus
). The problem is that the bichirs easily available to me are about 3" long and about as big around as a pencil. I worry both that they are of a size to be gobbled by my grown Bushfish, and that the 30" from substrate to surface might be more than they want to swim to gulp their air.
So, the question: Should I set up the 20 long I have with a locking lid to grow the bichirs out for a couple of months? It'd be a sand bottom, couple of flower pots, ambient light only, internal filter. How big should I get the bichirs before putting them in the main tank, or can I just pop them in there?
