thats a hard way to learn! iv just got 2 of the submersible filters with sponge and the air pumps (same thing i think) chucked in 6 tiger barbs so that it could cycle and just added 2 of my plecs. then next week im going to add my baby fronts and fhs, then 2 weeks after that i will add my bichir and talking catfish. yes i am aware that this would be over crowding but when the fronts and fhs get too around 4inches they will be going in to a 6ft tank, so this really is just a grow out for the moment. so what are you keeping now?
