Hi guys I need your help. My res (about a year old) had RI about 3 weeks ago. I went to a vet and he said it's RI and give us antibiotics to orally give, after the dose ended (it was for 7 days) I kept my turtle in a quarantine for another week and then moved her back to a bigger tank with another turtle (same age) . Now she acts perfectly fine (eats properly, no lopsidedness, no lethargy) but she occasionally starts bitting the air and blowing bubbles and does that like every 20 minutes(for like a minute then goes back to swimming). Anyone know why she does this?(I have a heater, I use a dechlorinator on my water, a decent filter and change water every 2 weeks, also a UVB light above a decent sized basking platform). Please someone help I'm worried for my turtle
