It looks like Ich, but its not.... any ideas

[mattsilvester]

Hi Folks,

I have just finished a "35 day course" of hyposalinity, followed to the letter of the law....... and thankfulyl my fish are all ich free.

But my purple tank has some large white spots on him that he cannot seem to shake. They are not ich spots.... they are a little bigger, and I have observed this for a while now and am wholly satisfied it is not ich.....

Now the poor little guy has been having a hard time - he didn;t especialyl enjoy the hypo salinity conditions (I don;t think red sea fish do, in general), and has been getting a bit of a hard time from my emperor angel as well..... which has left him a little tatty and pale, but thnakfully - ich free. This situation was not ideal, but it was the best I could do, and it was literally a case of "the needs of the few are outweighed by the needs of the many".

So.... now he has a few big white spots, which look like ich spots but are abotu twice the size...... any ideas what it might be?

Since I have started increasing s.g. (its up to about 1.018 now) he has really ocloured up again and looks alot better, and I am hoping once he's back in "reef" conditions with LR et al that he'll be able to shae whatever it is he has........ but in the mean time, prudence is the best course...... so any input would be much apprecaited.

Cheers,

Matt

A picture would help.

Do a search for lympho - a viral disease akin to warts in humans. Often looks like large version of ich .. if so, rarely fatal, no cure, and fish's own immune system may eventually ward it off if you maintain good water qaulity and feed nutrtious food.

kevin - I'll try to get a pic ut between my poor photography skills and high manouverability of the tang I doubt I will get anything clear enough to make any meaningful diagnosis...... I will however try

Off to search for lympho...... should have thought of that myself.....

I reckon that hypo and purple tangs just don't mix very well, to be honest....... that is probably the cause...... maybe not.... we'll see.

Thanks,

Matt

If that is lympho, is it safe to put him with the rest? Or should it still be isolated till it subsides?

 

[kevin2000]

As I recall lympho is only contagious within the same species.

I would keep in QT until your confident that your dealing with lympho.

 

[mattsilvester]

I would keep him in Q-tine too, but unfortunately that is no possible.

Very briefly reason why:

Display got ich > too many fish and fish too big to isolate in smaller tanks> no corals at present> LR fit in a 75 gal tank > treat fish in main tank (240) > treatment finished > s.g. half way back up...... all is well apart from this one thing - and lympho is not contageous

Still trying to find some pics of this type of lympho..... I'm actualyl pretty sure now that this is what it is..... I just want to find a diagnosis pic to satisfy myself

THanks,

Matt
