Loner fish

Question
The fish I think is a zebra obliquiden {astatotilapia latifasciata, red fins and a yellowish side w/black stripes} but I could be wrong.  He ate a little bit this morning and has been moving around better but he didnt eat the 2nd feeding.  When I fed the others, he came up with them but didnt munch.  Thanks for confirming my thoughts against treating the tank!  He is more lively today than yesterday, do you think it might be the food he doesnt like? The others chow down! The ammonia was around .50 ppm {mg/l} so I put in about 4.5 teaspoons {half a dose} of Amquel plus.  Thanks for your help and concern and I hope im not becoming a pest.

Sorry for all the questions, I paid close attention today to the loner fish at the same spot at the top of the tank, not only is he staying in the same spot, he isnt eating either.  This may sound weird but he doesnt open and shut his mouth as much as the other active fish.  Would it be beneficial to put an antivirus like water conditioner in the water being that all the other fish are fine.  Thank you so much.

Dear Jay,
I'm very sorry to say but it sounds like you might have a very sick fish on your hands. Or one that is very, very timid. *I wouldn't treat for something you weren't sure of. *
Does this little fish show any signs of illness besides being listless and breathing slowly? Do you know what species he is?

Honestly, it's hard to say exactly what for you to do because I cannot see the little fish and it is so uncertain as if he is sick or not. He could even have an illness you cannot see from the outside. But most fish display some kind of symptoms in one way or another.

Knowing the species of fish would be excellent though. ~Perhaps the water conditions are not good for him.

Feel free to keep me up to date on him if you do not mind.
I wish you only the very best with the little loner,
Karen~

No you're not becoming a pest!!! How silly of you to think that!

Wow, if your Cichlid is indeed a Obliquiden.. that is truly a unqiue little fish you have there! These are becoming rare in nature so preserving them is very important! I know how hard distinquishing cichlid species is. There are hundreds of african cichlid species each with color variants and different juvenile stages and also differences in males and females as you know.

Maybe the best thing you could do to indentify your cichlid is to go back to the petstore as soon as you can and find those same cichlids or ask the petstore workers about them.

You definately shouldn't have that high of ammonia. A better option and what I would do is a good 50% or larger water change to bring down such high ammonia levels. You're aquarium must still be cycling so I would be sure to not add anymore fish and continue with daily testing and doing those ever so vital 50% water changes when the levels are above safe bounds. Amquel is a very good water conditioner and will help with the ammonia levels but water changes are the best and most effective solution.

I really hope this helps! As always, feel free to keep me updated on your cichlids that is if you don't mind... ;-)
Best wishes,
Karen~
