lungfish keeping

So we recently purchased a lungfish from our local petvalu where it was kept in a 10 gallon tank we figured get him in a bigger tank considering the corona virus quarantine might be the death of this guy if the store closes and he is in this small tank this was about a month ago and heís now in a 4 foot long 75 gallon tank. Anyhow what Iíve noticed is thereís not much to find on lungfish keeping. So heís a African marbled lungfish scientific name is Protopterus Dolloi. His main diet is krill although we have played around to see what else he may like and heís ate frozen pinkyís (newborn mice), And brine shrimp. He has a 80 gallon biowheel filter that has a slow flow due to leaving a six inch gap of water between the water and the top of the tank. A heater is also running in his tank. We feed him 3 times a day usually a good ration of krill about every six hours and he seems happy most of the time. His personality is strange he mostly just hangs out either looking at me of the fish in our other 75 gallon heís in the line of sight of. So the problem weíre facing is ammonia in his tank we did multiple test so far. The first test we did about a week ago was at a hard 4.0 ppm we did a 70% water change which brought it down to a 2.0 on my next text I checked again just now and it is again at a 4.0. Iím not sure what to do about it at this point. Iím assuming that he is creating this ammonia his self. I put the appropriate amount of ammonia nullifier in his tank after the test. Anybody have some advice or knowledge on this subject?

Cut back on feeding him and do 50% pwc again to get the ammonia down to .25 or ideally 0.

some basics with information on growing beneficial bacteria and maintaining the nitrification cycle in your tank.

Fish in cycling



Shrimp especially turns to ammonia very fast. Try feeding less shrimp and like 1-2 at a time and make sure he eats them before offering an additional serving.
