Read the previous post entitled "Possible female lungfish" to get details of her history. I feed daily, or every other day. She eats on average 6 algae wafers, 2-3 peeled raw shrimp, and maybe a few silversides. She lives with many other fishes, so i make sure they all get a nice share.
a well-fed SAL kept in a large tank with the right diet, water change volume/frequency, temperature, (and genetics) can reach 24" in their first year. a fellow lungfish keeper i know has done this and the fish is truly an impressive specimen. overall a great species to keep if you are into lungfishes and want to maintain some sort of predatory community tank--
