I felt guilty about my negative "crack" on Lungfish in the "Ancient fish section sub-forums" over my favorite fish, the bowfin, so I bought one to give it a fair shake and try it out.
I asked the LFS store owner about compatability of this fish (9") with other ancient members of a tank that I planned on putting them in. They said no problema with my 12"+ Black Ghost Knife and three 6" - 8" Albino Senegal Bichirs.
Well, The african lung fish lasted less that two hours before being skinned alive and devoured. The LFS was right, and no agression between the ancients. I failed to inquire about the other tankmates not even a bit worried about them. Don't make my mistake!
I have had a spawn of baby Jewel Cichlids (Female red & Male electric blue jewel). The Female (around half the size of the male) killed it soon after the fry were born, I moved the fry & mother into the ancient tank for "feeders".
Around 20 of the fry survived past feeder size, and are now around 2". They LITERALLY skinned the Lungfish within the first hour! Holy Crap! I SWORE that my screwup as a newbie with a small electric blue J.D. sneaking through a tank divider into the section with a juvinile gar being my GUINESS BOOK OF WORLD RECORDS most expensive feeder fish ($45) in my fishkeeping career. Well two years of experience and I just topped that with a $65 feeder Lungfish.
I did get an excellent Retropennis Bichir at half price ($15) as a replacement. I did not risk putting it in the ancient tank, and it is doing great in the Malawi African cichlid tank!
I thought rift lake cichlids were suppose to be more "agressive" than Riverine Jewels!
Guess not. In fact, I have to 100% disagree with ALL african cichlid keepers! I keep Nile, Buttikoferi, Polleni & Bleekeri Tilapia cichlids, and none of the mbuna I have EVER kept would last ONE MINUTE with these natural born killers.
