To the original question. Not ideal but should be ok. The Ctenopoma (if the leopard bushfish) will greatly benefit from cover. As you know he likes to hide in his cave and another great idea is to have floating cover. Mine love to have the floating turtle fake wood platforms to hide underneath, and this makes them more secure and outgoing. In a shallower tank this will feel more like a cave and may stop him using his hideout so much.
im waiting for my plants to take over. Give it half a year and whole top of tank will be covered with plants.
I would love to add floating plants but sadly i cant with how i build my sump.
the java ferns and anubias keep duplicating so every week i stick 10 of those each to the woods. So the plant part is going great.
Some floating wood would be nice indeed but first i need to make sure it doesnt get sucked into the drain.
I mean cover enough i cant even see him hahaha
there are 4 bichirs in here,
1 hoplo catfish
1 eel catfish
1 butterflyfish
1 hejuta gar
1 ctenopoma
2 gold eels
zero agression, no napped fins, perfect harmony with a lot of predator fish. idk how it works but i love it.
They are laying sometimes with 4 bichirs and 2 eels and the hoplo catfish in the wood cave. its so adorable, it literally doesn't even fit .
the sump is also great, its almost just as big as the tank itself, so ammonia is close to 0, at friday its a bit but then with 40% water change and everythings close to 0 again.
