Am I taking on more then space allows if I attempt to breed Panaque maccus, Ancistrus sp.3, Rineloricaria eigenmanni and 2-4 species of Corydoras. I currently have all the fish in the tanks, before I moved and set this up the Bristlenose were spawning frequently, the Rineloricaria have spawned a couple of times (raised fry to saleable size once

With this setup I hope to breed all the fish a few times, give them frequent "breaks" (separating the sexes) and spread the fry throughout the tanks. I don't want more fry then I can handle. NOT breeding to make money...its a hobby

So is it possible or am I aiming a bit too high???
All the tanks are overfiltered with sponge and box filters. I do 10% daily water changes with good quality water.
Also can someone advise on power mechanical filtration for the P. maccus tank? Current running a 1000l/h eheim canister and it struggles due to design and flow rate I think. And its bulky on a 3' tank and a pain to clean.
Thanks.
