Hi I planning to add more tanks to the one`s I have in the near furture. . I do have fairly limited space. I was thinking of using 10 gallon tanks for breeding Apisto. and Pelvicachromis instead of 15 gallon tanks. I don`t want to waste any space and use as many tanks I can in the area where I be setting up the tanks. I would like your opinion about using 10 gallon tank instead of 15 gallon tank. Thank You George
