These tanks are used for breeding and raising fish, the left most 200litre is currently growing out juveniles, the middle has some young Apisto borelli in it, the right one has some rare Rhadinocentrus ornatus adults, which I am trying o breed from. I have another dozen or so breeding tanks, most in an understairs cupboard.What's in the small tanks? juveniles?
Nearly all use air driven sponge filters, some like the 200l under the big tank uses a corner style Hamburg matten filter, which is also air driven.How do you filter your small tanks? air driven or small canisters or else?
Nice fish those Radinocentrus btw
