Hey everyone! Been a while since I been on this site, mainly because I forgot my old account name and password. But I'm back with a new one. And I would like to say this site has given me so much information about my bettas in the past. Thank you.
Now...to get to my problem.
I've had a dragon scale betta for about 3 weeks now that I got from Petsmart. He was doing great for the first 2 weeks. He's in a 10g with a couple corys who he had no problem with. But this past week he became very depressed/lethargic. I actually thought he was dead a couple times because he was floating sideways, but kick started when i tapped the glass. I don't understand. He was super active at first then became limp. Any ideas on what can be happening? Thanks in advance.
