Just like the title says. I would like to keep at tank with just dats. I dont care if they are all the same species. I just think it would look awesome. Here's is the question. Has any one tried this? What success/failure did you have? What breed would you recommend to try this with? and how many would you start with? If achievable, I would like to grow out from as small as possible.The tank will be a bare bottom 6X2X2, with a 75 g sump
