I am currently stocking my 90g, just recently purchased the clean up crew - two rubberlip plecos and 5 otos. I was thinking about getting a pair of kribs and a pair of GBRs. The tank is moderately to fully planted with a couple large pieces of driftwood and a clay pot surrounded by flora. I have a sand substrate and when I had the LFS check my water yesterday I had readings of .25 ammonia, .1 nitrite, 20 ppm ammonia*, and a ph around 7.4. I just added the driftwood to the tank and ph out of tap is 8.2+. I know kribs generally hang out at bottom of tank, but am not sure of the rams. Would there be enough hiding places/swimming areas for a pair of each. I plan on stocking the tank with cardinal tetras(10-12), maybe a couple killifish, and another school of zebra danios(8 or 10). I was thinking of some kuhli loaches as well, they have been a favorite of mine since I was a kid and have now found out that they are more personable within a school. Ok, those are my stocking plans, was really wondering about the GBRs and Kribs, but you all can give your opinion on the rest of my selection as well.
