Help - Case of Brooklynella?

[OzarksReef]

I purchased this clownfish 2 days ago. She is in quarantine and looked just awful after the first day. She had a thin white coating on the right side of her body that was kind of "sloughing" off. I gave her a formalin dip (actually in a high concentration of quick cure) for about 45 minutes and then treated her quarantine tank with 10 drops of quick cure (it's a 10-gallon tank).

She is starting to look a little better and is no longer just laying on the bottom of the tank. The white coating is gone, but has been replaced by what white "bumps" on the same side. This is too large to be ick. Do you think it is a secondary infection from brooklynella - or some other type of parasite?

Any recommendations for her continued treatment? Thanks for your help!

sometimes ick and velvet get mixed up in diagnosis they are so similar in appearance maby this would help you to determine which one your clown has

velvet

Velvet is a parasite which appears similar to and is often confused with ich. The difference is that velvet covers mostly the body of the fish and is a smaller "powder/dust" instead of salt like bumps. The parasite moves from fish to fish in the form of flagellated (tailed) spores, which can live away from the fish for at least 24 hours and probably much longer. It is usually introduced with new fish and can develop into a serious problem. Like similar diseases it can be caused by overcrowding, stress, or poor water conditions. The gills are usually the first thing affected, heavy infestations on the gills may kill the fish without causing any obvious signs of the disease. Velvet affects different species in different ways. Danios seem to be the most susceptible, but often show no discomfort. The disease is also persistent among killifish, anabantoids, goldfish and marine coral fish. This disease is highly contagious and can be fatal.

The life cycle of the parasites responsible for Velvet is similar to the ich parasite's life cycle.
Dinospores form a root like structure and become parasitic on skin, fins and gills.
After 3 - 7 days mature parasites fall away and swell up.
Each cell divides inside a cellulose cyst, producing over 200 spores.
The spore, so-called dinospores are released and have two obvious flagella
These change into mature dinospores as they complete the infection cycle. They can survive for several days without a fish host.

Ick

Ich appears as small white bumps on your fish's body and/or fins resembling grains of sand. Unless you have all white fish, Ich is easy to spot. It is one of the most common and widespread diseases in home aquariums. Many say that Ich is caused by rapid water temperature fluctuations, rapid changes in water conditions, adding new fish or poor water quality. The fact is these events can all cause stress in the fish, which in turn weakens the fish's immune system making the fish more susceptible to the disease. Ich is often dormant in the tank unnoticed until a fish comes under enough stress to be affected by the disease. If caught in time the disease can be easily cured. If not it can become lethal. The protozoans that cause Ich have a three phase life cycle. It is this life cycle that makes Ich so contagious.

Adult/Mature Phase - Mature parasites are embedded in the skin or gills of the fish, causing irritation and the appearance of small white bumps. As the parasite grows it feeds on the red blood cells and skin cells of the fish. After a few days it bores itself out of the fish and falls to the bottom of the aquarium. This leaves a lesion on the fish which also makes it vulnerable to secondary bacterial infections.

Cyst phase - After the adult parasite falls to the bottom of the aquarium, it forms a gelatinous capsule around itself or cyst which allows rapid cell division to occur. This produces hundreds of young parasites or 'swarmers'.

Free swimming phase - after the cyst phase, about 1000 free swimming young swim upwards looking for a host. If a host is not found within a short time, the parasite dies. Once a host is found the whole cycle starts over.

The time taken for the life cycle to turn full circle varies with the water temperature, being a lot faster in tropical than in temperate conditions. In Ichthyophthirius, the complete cycle can take about 3-4 days at 21°C(70°F). At lower temperatures (10°C/50°F) this period can extend out to at least 5 weeks. At even lower temperatures the parasite can lie dormant for some time.

Cryptocaryon is more dependent on high temperatures and rarely causes problems below 20°C (68°F).
