Well, this plan is for my 125 gal, so that should be large enough for the smaller species of stingrays... And my african fish have acclimated to the soft water, low PH conditions in my tank, and they seem to be thriving. My Polypterus has more than trippled in size in the past year. My PH is 6.5, but I don't know the exact hardness. It is on the soft side, though. All in all, the tank conditions are good for a stingray, according to the research I've done online. I just wonder about how it would get along with the other fish. I've never seen my Polypterus or Ropefish try to bite any of the other fish in my tank, but I don't have any slow moving fish aside from my plecos. I do plan on getting rid of the large plecos, though... Anybody looking for a 12-14 pleco? I have on common and one albino that size. I'd love to collect some fancy plecos, though... Do you think smaller species of pleco would do better with stingrays than the larger plecos?
Thanks!
