I bought a lungfish yesterday and I am pretty sure its a west african. I will post pics in a bit to see if you agree. I was curious if he is a WAL how long will a 90gl hold him? He is roughly 8" right now. The tank is 18" wide and 4' long. Also I was thinking of getting a kiddy pool and setting that up for him would that be okay? I plan on feeding him bloodworms, shrimp, and hikari carnivor pellets as his main diet. Then night crawlers and feeders as a treat yes I know the risk of feeders but they would be kept in a seperate tank for at least a month before I feed them to him and this would be only an once and a while thing. I can't remember what fish was suggested to feed them thats store bought I would get some of that and feed it, would octopus be okay to feed as well? I also have muscle cubes I could feed him, maybe some ghost shrimp and crawdads as well. Is there anything else you would suggest to add to his diet? I know the basic care just want to run this by you to make sure it was right and I can't find their growth rate so I was curious of that.
