Hi, im new to this site and desperately need help with one of my fish. Ive had a 10 gallon for a couple of months and one of my most recent additions is a pair of dalmatian mollies. One of them was rather small but thats likely just because hes young. I noticed the smaller of the pair resting on the bottom of the tank, but going up for food relatively easily. I bought some peas after work in hopes that he may just be feeling sick from constipation or something of the sort. I have him floating within the tank in a betta cup so he can rest and go up for food easily. My tank is freshwater but after some research last night i bought some aquarium salt in hopes that he would respond well. I added it a few hours ago (a very small amount in the cup), but he seems to be getting worse! His eyes are swollen and seem a little white on the eyelids (I cant tell if its his color or if its something different). He has begun to flop around on his sides and is floating generally facing up vertically. Im assuming its a swim bladder problem but im finding lots of conflicting information. Im hoping i can get some help!
