I have a 20 gallon long tank which currently houses 4 panda cories and 2 ghost shrimp. If I can find more Pandas in my area I will definitely be adding 2 or 3 more to help them be comfortable. Also will probably add more shrimp cause I think they're kind of cool looking.
My city water site says that my water is soft, (< 10ppm CaCO3)
PH is around 6.4-6.6 (both in tank and from tap)
Tank is cycled, consistently with no discernible ammonia, nitrites, and around 5 ppm nitrates thanks to the plants I've got in there.
I have sand substrate, live plants, diy rock caves, an HOB filter with adjustable flow and a sponge filter, temp stays around 76-78.
Now to the question, given 6-7 panda cories and a few shrimp, I would like to add a school of 6-8 neon tetras and then a gourami. I'm thinking that I have the option of either Honey or Dwarf. First off, would a Gourami likely be comfortable in my tank, would it bully my pandas or shrimp? And which would you recommend for someone looking for a peaceful community, and as a first time Gourami owner?
