Good tankmates for a dwarf gourami?
I'm looking for some stocking suggestions for my 20 gallon (high) planted tank. I finished my fishless cycle and started (slowly) adding fish about a month and a half ago. I currently have:
4 Sterba's cory cats
1 dwarf gourami
1 zebra nerite snail
I added one male guppy to my tank this week, and unfortunately the gourami started nipping at him and the guppy did not survive. I had done research prior to adding the guppy, but apparently not enough. I haven't had any trouble with the gourami and the cory cats. I want to make sure that the next fish I add will do well in my tank community!
I am considering fish like danios, mollies, platies, or tetras. I'm a little worried about the tetras, because my tank has hard water and high pH (~8.2). I am very open to suggestions, and would appreciate any advice!
