My Poor Clown Fish

[intarsiabox]

Sounds like low oxygen levels in the tank. Is the tank covered, using a skimmer?

Lid? You have a lid on your tank? Tell us more. I tend to agree with intarsiabox in that your O2 may be low if the lid you're referring to is keeping things tight. There has to be a good gas/air exchange at the water surface and your lid may be hampering that process. The more fish/livestock you add, the more O2 is required.

Best to keep the clownfish numbers to 1 or 2 if they are paired. Others will eventually be taken out by the dominant pair in a closed system.

Firstly if you don't have a skimmer or adequate water flow your oxygen lvls are probably too low.

Secondly while certain parasites do show up on the body of a fish like ich they can take up residence in the gills as well which will also cause breathing issues.

Lastly a dwarf angel is probably the last fish you add to a tank as they tend to be the most aggressive, and 2 tangs in a 90 gallon isn't really recommended.

ok I do have a lid on the tak. I have a skimmer, a 1500gph return pump, and 4 800gph power heads. I am getting good surface circulation.

I am thinking you are correct about the parasites. can anyone lead me in the best direction for dealing with them? all of the treatments I have read about involve removing fish from the tank so you don't kill the invertebrates and coral. at this point I don't have a hospital tank..... for do I think I could ketch them without ripping down the full tank.

thanks for your help.

Most medications are copper based, which would kill inverts, you do get some that are not copper based but the best is to run your main tank fallow and treat the fish elsewhere as most parasites have multiple life stages such as ich which has 4, and some stages are resistant to medication.

So after 2 weeks of not seeing anything on my fish..... I posted this at my office and when I got home. My regal tang has spots oh it

I feel like now it is for sure a parasite and I just need to figure out a solution.

its a sad day

I would recommend at least doing ttm before new fish additions, specifically tangs as they are prone to ich.

First thought is ich/velvet or another parasite with that many new additions and the tangs and lots of clown fish there is probably incredible amount of stress in the tank , 90g is small to have 6 clowns in . And imo not qt any fish opens your self up to the risk of bringing in pests , the only other thing it could be (not sure how established your tank is or your set up) but double check your ammonia level . The low fish and breathing I have seen in my QT tanks when there is an ammonia spike it affects the fishy gills and the exchange of gas and chemicals and they can't deal with high ammonia but if that is good . I would error on the side of a parasite or ich and take the proper precautions and hospitalized as treat your fish
