Okay team, here's the situation of my three freshwater tanks: 5 gallon 5 pygmy cory catfish 3 rasbora espei 10 gallon 1 sunset honey gourami 4 cardinal tetras 1 zebra danio 29 gallon (coming soon!) rosy barbs ? So, my girlfriend and I are getting a 29 gallon for a christmas present to one another and she is dead set on rosy barbs. This is a must. I was thinking though, that I could move some of the fish around and still end up with what I ultimately want (a puffer!). I was thinking of moving the rasbora espeis to the 10 gallon, and the cories to the 29 gallon. The danio would move to the 29. This now frees up the 5 gallon to put a single dwarf puffer. Sound good? Also, how many rosy barbs would be good for the 29? Any other fish you would recommend me researching? I am aware that some (if not all) of the tanks are overstocked or getting there. Do know that I perform very regular water changes and have a really good test kit to keep on top of the levels. All of the tanks are well planted. Thanks for the input, I really appreciate your expertise! David.
