I have a 30 gallon tank (well planted) with three silver hatchets, a school of 8 sherpae tetras........and I brought home a flame dwarf gouarami last night (am expecting to get at least two more DG). My problem: Those sherpae tetras are harassing the poor dwarf gourami, nipping his fins and actually laying in wait for him. All I want is peace in my tank. When I got up this morning, things seemed a bit better, but I fear the sherpae tetras will need to be taken back.....I have only had them for two weeks, so no bond has developed.
The comment and questions are: Why are these little fin nipping tetras sold as community fish (is it just the feng shui of my tank?) and what tetras or other middle swimming school of fish should I get that are colorful and peaceful? Thank you for any guidance.
