My flowerhorn still eats normally and swims normally as well. His belly just looks huge to me and I'm worried because he's my baby! Raised him from a fry. I did an epsom salt bath today for 10 minutes (that was about 4 hours ago) but nothing changed yet. He has a 75 gallon tank by himself (the pictures show him in the hospice tank, he was in there for 10 mins doing the salt soak). I have not been seeing him poop lately and I searched everywhere in his tank. I also rubbed his belly a little bit like some videos showed for bloating but nothing came out. Any advice is helpful. I've been doing a lot of water changes too. Sorry for the terrible pictures.
