Gourami floating on side/upside down

[Sharnae02]

I bought 2 blue dwarf gouramis yesterday, and also upgraded my tank to 70L. one of my gouamis is swimming ok but when he stops he floats to the top and seems to float sideways and upside down. could this have anything to do with the new tank? I used all the same water from my other tanks, aswell as gravel and filters. His tummy is looking bloated or swollen where as the other one is not

Swim bladder! No big deal, I've been told cucumber helps.

Ive delt with swim bladder once before, i will use epsom salts because my fish wont eat the pieces of peas
