I have one Barbonymus schwanenfeldi in the 15k for sure. I got him in 1996 and he is starting to look very ragged. I also have several Barbonymus altus in there too.The Syns in the tank are getting old.I had two Synodontus angelicus in the tank but only saw one when feeding the tank on Sunday. One I got in 1987 and the other in 1988. I do have a baby in with some grow up elephantnose in a 55g (208 l).I also have a few Synodontus budgetti and notata in the 15k.There is also a very old Hemisynodontus membranacea in the 15k (bought in 1990) and I have a young one in a 180. The young one is a show stopper. A truly king of the species. He is at present in a old fish room quality tank so only bad pics of him.I do keep other SynsS. Decora in the 810 and a 120S. euptera in 2 180's, 225S. Granulosa in a 120S. Multipunctata in 180S. petricola in 180I also have a number of fish I bought as S. angelica a couple of years ago at about 1" which turned out not to be them. They resmble S. aterrima but could be a natural occurring hybrid and they were imported from africa by the distributor.Thank you for the detailed response. Are the tinfoil barbs (Barbonymus schwanefeldii) in there? Do you keep species of synodontis in the 15k?
What about Nile Perch do you keep them? Or dorado?
Have you started the build on the big tank yet?
