i don't think so. i already put him back in the tank and i was just sitting in my chair that is next to the tank, watching him. he took a really long drink, roamed around a bit, came right up by me, and started to throw up the water. then is started to get bubbly as he kept lurching. he eventually went back into his warm hide. is there anything that could cause this? i have a vet appointment scheduled for the morning but i'm just really worried i'm doing something wrong
