why did my clown fish turn black?
 
Hello Everyone,

It was very interesting......

Yesterday night I put some new brine shrimp that I purchased in my tank and it was basically a big frozen piece and when my clow fish ate it, I noticed that it got black in the lower part of the body and one day past and it is still black, The fish looks completely happy and healthy, swimming happily with other fish like always.......

So I am wondering that it turned black because the shrimp was frozen!??????????? or maybe it was a new brand!!!!! I stopped feeding them brine shrimp for two weeks because I didnt have anymore, so I gave them pellets that were rich in nutrition,I started feeding them brine shrimp again yesterday for the first time and this happened!!!!!!!!



Will it go away?? any ideas???



let me know ASAP!!!!!!


Thanks for the help!!!

I do not know.

I will, however, mention that brine shrimp should not be a daily staple in a fish's diet. Brine are not the most nutritious of foods and are best used to stimulate a fish's appetite, especially newly acquired fish. This is off topic, but worth mentioning.

its possible that it changed over time and you didnt notice? i do know that clowns usually will darken up as it matures

This was my first instinct as well. Although it is a little unusual for a clown to change color in an aquarium without other clownfish present.

sometimes they change color when t hey finally mature sexually... yours might have become a female

well, not only it changed the color but also became stressed and started biting my butterfly fish so yesterday I added some medication for stress and for calming the fish

ALso, right after i notice the clown fish got darker orange-blackish, I changed the water and salt level was high so I performed a water change to fix the salinity level, so I am thinking that the color changed because of the high salt level which made her to have stress


I noticed after the water change, it got a little better and I'm waiting to see big changes after adding the (kordon brand) medication yesterday



thanks

I hope this works out for you. Sincerely.

That being said, I have to add some personal experiences after reading this thread. I would not hesitate to suggest that most fish deaths in marine aquariums are caused by quick, unnecessary reactions. Adding medications without cause generally causes more harm than good.

Bottom line, any time you are unsure of what you are observing, the best action is no action. Just sit back and wait. Unusual color changes, bumps, bruises, isolated white spots, black spots, and other random observations are best left alone until further evidence is available to provide direction for the proper action. The large majority of the time the fish will recover without incident, if the fishkeeper simply allows the natural immunity of the fish to do what it does best.
