I have some zoos that my uncle gave me awile ago and now it looks like the heads are roting away kind. I dont know the peramiters but it did a 20g water change two weeks ago and another one yesterday, also would they grow onto my other zoo that I just got. Thanks

Sorry, no one has gotten to you on this.
How long have you had them? They could just be acclimating to your system, different lights, flow, parameters, etc.

The first thing you want to do is make sure your parameters are all in check, that's where I would start. If nothing is way out of whack then it could be almost anything.
From your photo I don't necessarily see any rotting polyps or anything but you obviously see things differently then how we see in your photo. Have you noticed any pests or anything like that?
What is your set up like? lights, flow, things like that?
Let us know.

I agree with Capture. I really don't see anything. See if you can get a better shot

Well the angles I have to get at all the pics come out blury, 4 have died already, they have been in the tank for 3 months. I have one 4 foot 36w t5 actinic and 36w 1200K white and 2 2foot duel actinic 65w am 2 2foot 65w duel daylight. These are in the middle of the tank. Flow comes from a fluval 405 and rena filstar xp and a realy week power head that would be grat for a tank one foot long. Im Going to my lfs today so ill get the water tested.

get the water checked first and go from there.
Do you use RO (reverse osmosis) water?

try shaking them in fresh RO water and see if the culprit can be found
