I bought a male betta last week and had him in a 1G bowl. I felt really bad for him in that space so I ended up buying a 10G tank. I let it run with the filter on for 2 days and put him in. I realized after I should have let the tank cycle for a few weeks. I have checked for ammonia and it is at 0.
He now has a small filter, heater, cave, real bamboo, and fake plants. It's a pretty nice home if I do say so myself!
I picked him up at petsmart. I'm not sure if he is in the best health due to his prior living conditions (small cup, blue water, stress from being beside other males). He is flaring A LOT at me, his reflection, the filter, pretty much everything he sees. I'm worried he is really stressed out.
His fins seem a little droopy and frayed and sorta white. He is also trying to fight his own reflection almost constantly when not puffing up at the objects in his tank. He only seems comfortable around the bamboo.
I'm just worried about him as I want him to be happy. Not sure what is wrong with him (if there is anything wrong with him!). Temperature is at 78. Is it just going to take some time for him to adjust?
