Hello, I am new to the group and am still figuring out the site so if this isn't the place to post this then please let me know. I have 2 bichir fish, 1 is an endlicheri and the other is a Senegal. I've had them both for about a year now and have not had problems with either until about 9 or 10 days ago. My endli is at 10 inches and my Senegal is at 8 and a half. My endli started to develop a belly. They have feeder fish in the tank with them so at first I thought he just had a big meal. It's happened in the past but it goes down within about a day or 2. About 5 days after noticing the belly I noticed that it had not gone down at all, so I figured he may have been constipated. I talked to my local fish store and they suggested Epsom salt. They are in a 75 gallon tank, and the LFS suggested to put about 3 cups of salt in to help him use the bathroom. This is day 4 and his belly hasn't seemed to have gone down. He still swims back and forth in the tank, but I have noticed he is laying down a lot more than he usually does. He comes up for gulps of air on occasion and hangs out at the top for a little when he does (always right side up, never belly up or side up), and then slowly lowers himself down to the bottom again. His appetite has decreased though. They are eating feeder fish and Massivore pellets. I do plan on getting a floating log so he can hang out closer to the surface so he doesn't have to swim so high up to get a gulp of air. I'll post pictures when I figure out how to do so on this site haha so give me a few more minutes. Any help will be appreciated.
