So here I am, knew I'd wind up here eventually. I can no longer count the number of people I've successfully guided through Ich on one hand and of course I get the disease I can't diagnose. Let's cut the nonsense. Here's the scenario.

Two nights ago I noticed a scratchy white patch on the head of my male cackatoo. I've seen Ich enough to know that this is not it (judge for yourself of course). It is not fuzzy but smooth and initially looked like a broad scratch. In the 48 hours since it has not grow but filled out to a patch of smooth white. The fish, Rene, seems to be conducting business all-things-normal for now. He has been active and engaged and as of yet I have not caught him glancing off any surfaces.

Recent tank history has included the addition of six pseudomugil furcatus. I have considered that they may have tracked a disease in but everyone else in the tank is symptomless. The phenomenon is isolated to Rene. There have been no radical changes in water chemistry. The greatest potential for stress would be coming from a DIY CO2 mixture switch. The cats on the floor could intimidate him but he just swims overhead, outside of that he rules the tank.

So you'll be wanting the tank params no doubt. The pH reads consistently at seven even. NH3 and NO2 read 0ppm. NO3 comes in at 5-10ppm prior to w/c. KH registers 8 degrees. The tank is 20G planted with CO2 added at ~25ppm. Dissolved oxygen is high. The tank is running on a single Fluval 104 filter. Tank temp reads 80F degrees and is stable. Feedings to date have included Omega One Flake, Hikari frozen bloodworms, and Hikari sinking wafers (stolen from the cats, little piglet).

And a picture is worth a thousand words. Please help fellas. He really is the life of the party and I'd miss his puffy face staring back at me every time I walk through the door.

It just looks like he's lost a few scales, so as long as he's eating and the tank is in good shape he'll be ok. I'd be curious how he lost the scales

That's kinda what I figured but I'm just fishing for second opinions. If it's so that he lost some scales then I'd bet he wandered into the dominant zebra's cave again and got his *** handed to him. That cat has been a touch aggressive with that territory as of late and Rene's been dumb enough to stumble in there before. The same night I noticed the "missing scales" I watched the zebra pound on the elder snail in there for no less than five minutes. Poor Gerald Ford, first the bouyancy issues and then that. He's missing an eye stock now.

BTW 5 Points for anyone who spots the pl*co in that pic.
