My old guy Cleo was having troubles swimming and he was having troubles eating his food.. so I had to take him out of the 10 gallon. I switched him into the 3 gallon and put picasso into the 10...Cleo is now eating? and Picasso is hyper and happy! I added some new twigs to the 10 gallon:
I have been meaning to switch over to sand again but haven't had time to get around to it yet...I am thinking about leaving some of the gravel in the corners and edges of the tank to help anchor the plants and just do the sand in the open swimming area in the middle front.
