I've had my double tail for a few months now, but when I first got him, I noticed he had an oblong lump on either side of his body right before the tail. I thought it was probably some genetic defect, since double tails tend to be prone to things like that. I have since identified it (I'm pretty sure) as a swollen swim bladder.
He's a bit of an awkward swimmer, but it doesn't interfere with his day-to-day life. I've read that many double tails have this problem because of their shorter bodies, but I havn't heard whether it's detrimental or life threatening, or if there is any way to cure it.
Like I said, he can get around the tank fine, he just has trouble with things like turning and sometimes tilts to one side a bit when he's resting. Does anyone have any information on swim bladder disorder for me?
Thanks guys! :D
