I have a Rasbora with what looks like swim bladder, do you think you could help? It is a Espei Rasbora in a tank with three other Espei Rasbora, one harlequin, a Nerite snail and millions of pond snails. It's a ten gallon tank, heated to 79, with a twenty gallon filter.,I've had one guppy and one Espei die in the past week out of the blue, the guppy was two years old and the Rasboras are about 20 months old. One of the Rasboras keeps sinking at its tail end, and then swimming up. It's like it has a weight on its tail. It's not bloated or anything.
Is there any meds you think I could use on it?
THANKYOU so much!
I have Epsom salt, aquarium salt and metronidazole on hand.
