Lost my tang and a clown? no idea why

[Daniel475]

i was told to leave my light off to let the shrimp clean whatever was on them off? should i turn my tank light on?? and it has a marineland filter it pushes alot of water in there for sure.. and there is alot of surface movment on the water

I Think this was an oxygen issue, like the others have touched on. Tangs love oxygenated water, which sounds like there wasn't alot to begin with, since the aquarium is only 30 gallons and only water movement is from a marineland filter. Tangs need alot of space 30 gallons wouldn't have cut it and most tangs need at least a four foot long tank to swim in.

the marineland is for a 50 gallon is pushes quite a bit of water.. should i turn the light on the save my last clown??? the reason i got the tang was because i was going to upgrade to a 125 .. but so far this takes some time to get used to.. the all the fish last night almost looked like they were shedding.. not to sure what went wrong exactly but sure dont like losing fish

1. Your tank likely did not finish cycling because your ammonia and nitrite readings should be zero at all times. As tjere was no scratching or gasping for air, this was the likely cause of the death of all you fish.
2. Once you have measured to ensure you have zero readings you should wait one month before you add fish and than only add one fish each month. Success in this hobby relies on patience.
3. Did you tell your LFS you only have a 30 gallon tank?
Tangs require a 6' tank that provides them with the swimming room they need. Please wait until you have a suitable tank to accommodate a tang.

yes i told him that but i was planning on upgrading pretty soon, well thanks for all the advice.. anything i can do to help this clown out.. salinity is at 29 .. which is like 1.023 i use a hydrometer i think i should get a refractometer.. and so should i turn the light on? and what was this shedding that was coming off the fish

There are three things you can do.
1. Immediately return it to the lfs.
2. See if another reefer will put it in his tank for you
3. Set up a small qt and put the fish in it until such time as your tank cycles.

A cleaner shrimp cleans night and day.

Hey Dan,

Sorry to hear about your fish . I just googled 'clown fish shedding' and came up with the below note from another forum.

"usually slime-coat shedding is a water quality issue. many times it is high ammonia or nitrite that stresses the fish's skin and the fish alliviates the pain by producing more protective slime."

Can you take a picture of the clown? It might help people identify what is specifically wrong with the fish. As suggested by others, you may want to set up a hospital tank and monitor the clown, that way if the sickness does become identifiable; ick, bacterial, etc.. you can treat.

ya i will get some pictures after work i think paul is coming over at 4 30 after work.. i tested for nitrate and it came back as 20.. says in the instructions if its at 50 its bad??? so ph read 8.0 nitrite was .1 really light and nitrate was 20

I'll come by too, if it's okay. I wouldn't mind seeing what you guys have done with the place since moving in. Also want to see your 125 FW set up.

What is your ammonia reading? If you have a reading then those numbers suggest to me that your tank is in fact in a cycle and still in fluctuation which can be quite taxing on fish. That compounded with what I also agree is a lack of oxygen is a very bad mix of scenarios for any inhabitants. I would follow Naesco's recommendations.
