I am new to the Betta world, and am in need of advice. I've had my boy for a week now, he was in a 1 gallon, but now is in a 3.5 gallon with a filter. His color seems to be coming in (he was very pale when I got him from the store) but I noticed he has a rip in his fin, worried it may be fin rot. I just moved him into his new 3.5 gallon two days ago and he's definitely enjoying the room (swimming all over the place).
The two pics are:
1. of him yesterday
2. of him today
Does fin rot happen this fast/over night? Or could he have caught his fin on something in the tank while swimming?
