Hi guys! I recently happened upon a 55g, that I'm now setting up to house cichlids. I'm very much a cichlid newbie (I've mostly only kept peaceful tropicals) so I'm trying to figure out the best combination. Tank has an Aqua-Clear 30-60 and a Tetra EX30. PH is about 8.0-8.2, hardness about 50ppm. Sand substrate, soon to have some rockwork. I think I've finally settled on the peacock species...they seem to fit what I have in mind the best. From my wanderings on the internet I've found it's possible to keep an all male peacock (aulonocara) tank, which is my intention. I'm curious as to what kind of numbers I should keep, I looked at that incredible website aqadvisor and my potential list seems to check out fine. My thought was 5-6 of various aulonocara species, all males, one OB, one red shoulder, one sunshine, etc. I was wondering if a hap borleyi would be fine in there as well...I really like them and would love one in my tank. I also wanted one "oddball" fish that I haven't decided on yet, was thinking an African Knifefish but I have little experience with them. Would it get too bullied by the peacocks? Was also concerned about feeding...I have experience at my store trying to get a black ghost knife to eat, and if the africans are anything like that I'm sure they wouldn't have a chance to eat before the peacocks got it. Any other suggestions as to an oddball fish? My last and wishful thinking question...I currently have a bristlenose pleco and two kuhlis "leftover" that I was considering trying with the peacocks. I'm not totally worried about the pleco, but I absolutely adore my kuhlis and I'd hate to see them slurped up like spaghetti ;D. I'd hate to part with them as well, sigh. I can't find any material that advises either way about it..hmm. If I provide enough rocky holes will they be unobtrusive enough to avoid being dinner? I do have a 10g they can be moved to if needed, but I guess you never know once the lights go out. Advice? Thanks in advance for reading my essay...I know I'm all over the place here .
