I have a heavily planted 55g with three pearl gourami and a small school of dwarf rainbow (“Skull Creek”) who all hang out in the top third of the tank. It also has 5 corydoras and a couple of kuhli loaches but I’m slowly catching those out to move to a sand bottom tank. I have super hard water and a ph of 8.2. I’ve been looking and looking for a colorful, active fish that will hang out in the bottom half, not the bottom. I’ve considered Bolivian rams or Kribs, with my water I’m leaning more toward Kribs, but I know there must be a plethora of fish I haven’t even thought of or come across. Apistos are a no go. Please! thoughts, ideas, suggestions, questions, I invite and welcome them all because I’m really tired of this tank looking half empty. Thoughts on the Kribensis idea?
