Hello! I need advice on a "centrepiece fish" for my 26 gallon tank. It is a long tank more than a tall one (only 16" tall and 31" long) and I already have 9 pepper corycats and plan on adding a school of tetras,probably neons, and two male endlers that I also already have. I fell in love with electric blue or German blue rams but their temperature requirements are too high for the little Cory's so off to find another option. I like honey and dwarf gourami's but I am open to other colourful options. I have a pH of about 7.0 and the tank is heavily planted with a sand substrate.
