Hi All, I have a 55 gallon tank which needs some restocking due to older fish passing. . I would like different opinions on whether to get a school of kuhli loaches or Cory cats. I have had Cory cats before and like them. I also have now 2 kuhlies, started out with 5 but lost a few along the way. Honestly I have been waiting for over a year for these 2 to go but they are going strong. Before they were in my 29 gallon but are now in the 55. Before I hardly saw them, but now I could get a really large school where hopefully they would be out more. Oh and these are brown, if I find banded ones are they the same species?
