Hey, I have an adult male angelfish, and he's been getting bloated and his eyes have been swelling a bit as well. My LFS said it was a intestinal infection and i should use methylene blue, maracyn, and metrozol as well as adding some bio-spira to the hospital tank? Is this correct or does my LFS have no idea what it's doing?

need more info in order to help you.

what size is the fish.
what size tank is it in.
what are your ammonia, nitrite and nitrate levels.
any other fish in the tank?
if so, what kind and how many.
how often do you do water changes.
how much do you change each time.
do you perform gravel vacuums.
if so how often.

The fish is about 4 inches tall, lives in a 125 gallon community tank. Ammonia 0, nitrite 0 , nitrate 10. The tank has 3 clown loaches, 2 pearl gouramis, 2 blue gouramis, a gold gourami, a opaline gourami, a school of cardinal tetras, a yellow tail spiny eel, and a peacock eel. I do water changes once every 2 weeks or so with my python

sami, your water quality seems fine which is interesting since bloat/dropsy has as its primary cause, water quality issues.

if you want to try medicating this fish here's what i'd suggest. first, methylene blue and metrozol are not effective in treating dropsy. Dropsy, is actually a "symptom" and not a disease in itself. the blown up appearance of the fish is the result of swelling within the tissues and organs of the fish due to a build up of fluids in the kidneys and an inability to excrete this fluid in a normal manner. in other words, advanced kidney disfunction.

the problem with treating this disease is that there are a number of "potential" causes: bacterial infection, parasites, cancerous tumors, virus, internal fungal infections or sudden temperature drop of more than 3 degrees.

If the cause is bacterial, the swelling typically comes on pretty rapidly. if swelling is gradual then one or more of the other potential causes are more likely. unfortunately, treatment is most often useless at this point due to the advanced state of the disease process. When the illness, whatever the cause, has progressed far enough to cause internal swelling, the concommitant internal damage is usually too extensive to be repairable.

if the disease cause is bacterial and if the disease process is caught early enough, treatment with Romet B, a broad spectrum antibacterial, *may* be effective when used concurrent with an increase in water temperature to 84-86F for 2 weeks minimum.

BE CERTAIN to maintain HIGH OXYGEN LEVELS during such treatment since at these temperatures, water holds significantly less oxygen at these higher water temperatures. one of the suspected bacterial precursers to the disease process -- Aeromonas, is killed at these temperatures.

concurrently add 1/8 teaspoon of EPSOM SALT -- per 5 gallons of water. feeding foods soaked in ERYTHROMYCIN will kill the second suspected bacteria, Mycobacterium. in rare cases popeye has been found to be caused by Edwardsiella etarda. this is found *only* in fish that have been bred in outdoor ponds -- the functional bacteria in this case is carried by frogs. while fair to good results in treatment have been found by feeding Romet B., even better results have been found using injectable chloramphenicol or amakacin. this is best done by your veterinarian.

If parasites are a known cause, treat for them first for 3 days increasing the temperature to 86F as fast as possible.

EPSOM SALT may help reduce the internal pressure casued by the swelling. extremely good aeration is necessary here due to the use of such high temperatures.

NEVER USE SALT (sodium chloride, a.k.a aquarium salt) for treatment of dropsy. this will KILL your fish in a very short time. the affected fish are already having a difficult time getting rid of salts due to kidney disfunction. this causes the blown up appearance and concurrent scale standing. the osmotic inbalance caused by addition of sodium to your tank water will make this condition far worse.

EPSOM SALT on the other hand, does not pass through the walls of the gut or gills and will extract water OUT of the surrounding tissue into the gut where it *may* be excreted.

The thing that confuses me is that it's not dropsy, the signature "pine cone" look is not there. The angelfish is fat and has puffy eyes.

standing scales (pine cone) is usually but not always a tell tale sign of dropsy ... in the absence of any other information, i'd treat this fish as if it had dropsy.
