Just need some quick help with a school of bleeding heart tetras! I have 12 BHTs in a 60 gallon tank, I wanted to expand the community so I added 3 powdered blue gouramis. So far the gouramis keep to themselves, but the BHTs won't leave them alone, they are constantly following them around and fin nipping! It has only been 24 hours since the addition of the new fish, so should I wait for awhile longer to see if they all calm down, or in the best interest of the gouramis, should I return them to the store with the hopes they find less harassment in a new home? Hate to take these gouramis back, they are quite stunning! Thanks!!
