One of my fish is bobbing at the top of my aquarium, partialy out of the water. It appears healthy except for the fact that it doesnt seem to be able to be able to control its boyancy. Is this a swim bladder problem?

Hey Baran, welcome to ACF!!

Could be a physical problem, but could also be caused by stress.

What size tank and what is the stocklist? What type of filtration?

What are the water parameters, i.e. ammonia/ nitrites/ nitrates/ pH/ temperature?

Is this fish being picked on or excessively chased/ harassed?

Is this fish eating normally? Any abnormal or stringy feces?

How long has it had this problem? How long has it been in this tank?

The tank is a 55 gal. I have a Fluval 205 and a 305. I usually also run an aquaclear 110 as well, but it currently is not functioning. The ph is kept at 8.2. Not certain on the nitrites etc, but since noticing the problem about a week ago, I bought some products to control the Nitrates, nitrites and amonia. I have been doing water changes, 25%, every other day.
The fish is new to the tank, a little over two months now. I did notice some stringy feces and it appears to have a swollen abdomin. The fish was picked on for the first couple of days, but not after the initial release. It seems to have an appetite.

I posted a picture of this fish on the ID Forum. Otopharynx sp.

Do you have another tank that you could move him to, preferably by himself? Either way I'd do the following-

Start by adding 1/2 cup of epsom salt to the tank, feed lightly, and leave the lights off for a few days.

If after a few days it is still the same, we'll move on to plan "B".

I do have a hospital tank that i keep running, but I have a fish from an other tank in it currently. I could move it to a 12gal. I have running with only a cory and a pleco in it. I will give it a go. THANK YOU so much for the help!

Just realized I should have been more clear on the epsom salt dosage.

Normal dosage is 1 cup/ 100 gallons tank water. Can go up to 2 cups/ 100 gallons, if desired.

Is conditioning salt ok, or must it be epsom?

epsom salt works best for any problems. I just had a problem with my frontosa, he had clamped fins and was swimming very eradic. Put in two cups for 165 gallons and he was out swimming by the morning with no problems.

The conditioning salt is good for increasing slime coat. Or just a general tonic to reduce stress or can even be used to make a salt dip for your fish.

Ok, I added Epsom and have the lights out. We'll see what happens. I rarely see my frontosa. It usually only peeks its head out at feedings.
