I have, what has become, a fairly good size Dojo Loach. He is a pig who eats a lot and fast..more than the GF!!!
But lately when he eats, his tail starts to float up. He swims around for a bit...then goes back to eat...and can't keep his tail down. Stays like this for awhile after he eats.
Maybe he is constibated? Or worse? Or nothing at all?
THANKS!
