OK, I have a few questions, more or less suggestions, so I want to see what you have to think. My first is a question. I was wondering how many DP's and ottos can go into a 6 gallon? 2DPs and 2 ottos?? Also, I may also wait on the DP idea and put some of my bettas in the 6 and divide it, wait until the GSP is ready for the big tank (60) and then get some DP's for the 20. What do you guys think I should do?
