Betta at bottom
I use test strips for the chlorine, nitrite, nitrate, PH. Liquid drops for the ammonia levels. I had not filtration in the small tank, and have not yet hooked up his new filter in this tank. I was having problems assembling it. Wasn't sure if that would upset him more. I put his two plastic & silk plants, and a little bridge in the new tank. I put everything in the same positions as in the old tank. This morning I added a little pagoda, thinking maybe he feels too exposed. He is still on the bottom.
