Ich after dark cycle

[CarlDelain]

So i had a cyano problem and tried a dark cycle and then i came back and turned the lights on after 3 days and one of my allardi clowns is missing and my other allardi and flame angel have a really bad ich problem
I don't have a quarantine tank and my reef is full of inverts and stuff. what should i do about this? And where could my other clown have gone? :/
The clowns were both still about an inch and a half long.

Your only choice if you want to address the issue is to set up a treatment tank, remove all fish from your main tank and leave your main tank without fish for 12 weeks. If this is not an option, keep your water quality up, feed good and hope for the best.

Buy a QT tank today, and get it ready. AquaClear hang on filters are convenient... adjustable flow, flexible media basket.

Start mixing lots of new water asap.

Make sure you have the best foods, and soak in supplements (Selcon or Zoe).

Test every water parameter, and identify every possible source of stress.

Resume your normal lighting schedule, as this was an obvious and recent change.

Your missing clown is probably hiding, or possibly disposed of by your cleanup crew. Also check your overflow, sump, and carpet.

Well doing the dark cycle could have cause the fish to have stress out and develop ich, but do some major water changes ASAP... atleast 25% a day... It may stress out your corals if you have some, but i would try that first... but in the future, i advise you getting a QT tank (20 Gallon w/ hang over filter will be fine) and you should not have a problem... Good Luck!

Yeah most of the signs of the "ich" are completely gone now. They're eating like normal so im assuming it was from stress. Still no other clown though i moved some rocks and no sign of him so im assuming he's gone
