V. Lionfish Eye   2/21/15
Hi Crew. I hope this email finds you well.
<Ah yes; thank you>
I have a V. Lionfish that is around 10" long. I have had him for around a year.
He has a tiny white dot that looks deep inside one eye and the other eye is completely black. I think he has had this for a while. I am not sure when I first noticed it or if he always had it. It does not look like it is on the surface and it is tiny like a pin point. I have not noticed any change in size at all.
<Eye issues as yours are very common w/ Pteroines... they don't like the typical "too-bright" light intensity of aquariums, and folks are wont to provide sufficient shaded cover... And there are many cases of nutritional issues which lead to eye troubles... and damage from run ins with other livestock, system...>

He eats crazy still and I see no signs there are sight issues or parasites
Any ideas on what this is or anything I should look at doing.
<The above... More hang overs to get out of the light; food supplementation (see WWM, Lionfish in particular re... the search tool (on every page), indices>
He is in my 150 FOWLR tank. Other fish include a Harlequin Tusk, Porcupine Puffer,
<Not really compatible...>

and Snowflake Eel.
<Welcome. Bob Fenner>

- Sick Lion Fish - my lion fish is acting funny came home floating upside down in tank switched him to another tank  please need help don't have a clue as to what happened  or why <Well... you'll have to be the detective here; I can only help you analyze the data you collect. How long have you had this fish? What size tank was it in? What size tank is it in now? How often do you change water on these tanks? What do you feed your lionfish? Who else lives in the tank with the lionfish? Have you run any water tests [salinity, ammonia, nitrite, nitrate, pH, etc.] - if so, what were the results? Please answer these questions and I might be better able to answer yours. Cheers, J -- >

Volitans Lion Fish Mouth Problem Please HELP!<MikeD here>  A co-worker has this fish and we are all worrying about it.  The lines of his pattern used to extend all the way to the edge of his lip.  We do not know what has happened, but there is now a concave white area above the lip a good 1/8 inch to 1/4 inch wide and he is not able to open his mouth very wide.  He is malingering and has been seen breathing very heavily.  I personally don't know anything about fishes, but am just an animal lover that can't stand to see any creature struggling for its life.  We don't think he's eating anything--the little guppies are still swimming around.  His owner used to put his finger in the water and the fish would swim up to check it out.  Now he just lays there.  This has been going on for a week or two.  Any ideas or suggestions? <Do to the limited information that you've supplied, there's truly not much that I can suggest. I suspect that part of the problem is that the salinity (salt) is too low, based upon the fact that you said the "guppies" were still swimming around.....if the salt is in the proper proportions, guppies usually won't last for more than an hour or so before expiring.  I'd also need to know about the other water parameters (ammonia, nitrite and nitrate levels) but I suspect that the problem is many pronged, 1) improper diet, 2) improper tank maintenance and 3) possibly a bacterial infection as well, as the discoloration MAY be an indication of a bacterial infection resulting from an injury, in which case you'll want to check with your local LFS about a good antibiotic, with several generally available.  As always, it's strongly suggested that that a small "hospital" or treatment tank be utilized for the medication as it will kill of all of the denitrifying bacteria in the main tank, making the problem even more severe.  In truth, the prospects for this particular fish sound grim, and trust me, I'm not saying this lightly as the Lionfish and their kin are among my favorites in the sea.> Thanks.
