erm.. can fish 'break wind' (or water as the case may be!) i keep seeing bubbles coming out my dojos back end..
at first i was like, what no they cant be coming from there, its just some loose bubbles in the tank.. but a few days later i was watching an noticed it again, and it definatly came from you know where.

is it normal

I dont have any dojos but I have seen my goldfish fart. At first I was just like you in thinking that it was just a bubble from the tank but then a few days later I actually saw a little bubble come right out his butt

I've said many times over that Dojo's are one of my most favorite fish.You are constantly shaking your head and laughing everytime that you're watching them.

lol, might have to get the goldies little clothes pegs for their noses!

If only they're in a 20-gallon tank...

i remembered that cartooon when i saw the bubbles appear from my goldie butt the other day!

i love the cartoon, so true. ive seen dojos do that, so funny when the little bubbles come out. they just swim off, like 'it wasnt me it was him' kinda thing.

omg the other day i saw the wierdest thing ever! Kirby my little dojo was lying on his side on the bottom with his mouth wide open, and he kept jolting and opening his mouth more as if he was choking.. but theres nothing to choke on then bubbles started coming out his butt.. then he looks as if he pushed really hard and lots of little bubbles shot across the tank i even heard the noise!
Where does it come from? swim bladder? because after he went straight up to the top.. took in some air (to refil the swimbladder?) and rested on the bottom looking quite releived
