I just got a small tank and a Beautiful Betta. He seems to like the tank, but stays away from the castle and caves. He likes to be near one of the two silk plants or the heater...or even just the bare area. But he doesn't go near the castle...which may be too large for the tank.....idk.
Bo is my first betta. He is in a tetra waterfall globe 1.8 gal, with a HT10 heater in it. In a month or so he will be moved into a 6 gal Chi...it is backordered. He does not mind the waterfall, he comes up to breathe and swims right through where the current from it would be.
Should I give him some time to get used to the larger living area and the castle or remove the castle to give him more swimming room?
I'll try to post a pic later.
