Is it possible to keep any species of tropheus in a standard 55 gallon tank? These fish have been calling me and I think im ready to try and keep them. I am a bit nervous because of the horror stories I hear but I've dealy with mbunas which have very similar requirements and I have also dealt with bloat so I think Im ready. I really like tropheus duboisi but I will keep any species really. Any other pointers are helpfull!
