fish help

I had a few blue reef chromis die in my sump. I figured they did not have enough space between the macro and rocks I have in there. Today one died in my display. My midas blenny seemed to try and bite his tail a bit and rubs against some rock really fast and rub something off of his side. I barely see some white specs on his face and side fins. Now my black cap bass let is running in to rocks to rub something off as well. Any reccomendations would be welcome.

No gasping. No wounds, no fraying, i don't notice a sheen. Black cap swims up to some fish and like yawns at them but that's it. Just crashing in to rocks and some white dots.

I had a fish trap in there for over a week and neither fish ever went in. So short of draining my water I don't know how I would get them out.

There are no in-tank cures for marine ich (cryptocaryon irritans). Even 'Rid-Ich' is just a control.

As far as Rid-Ich goes, I highly question it as a product. I haven't used it, so I can't speak to the efficacy. But, I can speak to the design. It's a combination of formalin (formaldehyde) and malachite green - two of the most dangerous drugs in the hobby. Formalin is incredibly easy to overdose, and then it breaks down quickly enough to require multiple doses. There's no test for it, so you're likely to kill your fish with an overdose or with an underdose rather than the parasite. Malachite green is carcinogenic and is an immunosuppressant. Long story short, this product might help, but these aren't medications I'd recommend using in a reef tank...and it won't even cure the fish.

For what its worth my advice would be to just make sure the fish keep eating. I am convinced that 95% of marine systems have ich in them.

Here is my feeding regiment-
I thaw frozen food in tank water and then strain out the water through a small net, let the food drip off excess moisture for a minute or so, apply a few drops of garlic and a few drops of Selcon. Let soak for a minute.
When feeding the fish I try to add the food slowly. My thought process is that I want the fish to consume the additives before it's diluted away.


I feel that the fish can overcome ich naturally with a good immune system. If a fish stops eating it's immune system will plummet. Garlic entices fish to eat and the Selcon delivers much needed vitamins.
In addition to frozen Mysis I also feed the Angel mix and a gel type food called HPD.

If a fish stops eating I will take more aggressive action by removing for a freshwater dip.


Your fish is flashing off the rocks and opening it's mouth because it wants to be cleaned. Do you have any cleaners?

For the record, I am new to the hobby and yes I have lost several fish and a couple corals.
