Great now I just need to source one, not very easy to find in the uk.The SA lungfish won't really eat smaller fish on purpose, but if they happen to be eating and a fish gets sucked in, it can do a lot of damage. Sometimes while eating a SA will accidentally slurp up a bichirs tail and cause it to bolt up or across the aquarium. It's a relative slow eater, constantly looking for food. What sucks is when you don't get their really large turd out in time, and they break the mucus membrane, causing all the pieces to spread throughout the tank.
Smallest fish in the tank would be the EBA so if they're fine I dont see any issues, the maintenance I'm happy with doing a bit extra for because I've wanted a lungfish for quite a while now.
Aye as you say the overstocking, plenty of space, plenty of places to hide and manuver, the excess of fry and keeping them well fed could be the reason they seem to get along so well all together.I wish I had an explanation for this but my tank is the calmest cichlid tank I have ever had or seen.
Here is a video of the tank look for the baby's, watch when I turn the flash on how many more you see. They are everywhere and they just swim right by the bigger fish and the lager ones just swim around like they don't have a care in the world. Very few lip locking mostly just a chase hear and there. I know I am very heavily stocked more than any other tank I have ever owned but it can't be just that. If I had to take a guess It's probably a combination of factors, like they are well fed, they have a lot of room to run. Maybe just the sheer number of baby's they got tired if eating them. But my population is growing exponentially and it is almost to the point that I am going to have to do something about it. The females just keep breeding its crazy. I have 2 females that seem to just stay pregnant I don't know when they eat?
