Hi,

Some time ago I left a friend come to my place to feed my fishes, including a small C. foai "colony" (2M/6F). Unfortunately this person found it annoying to have to remove the canopy everyday and decided to leave it off (it's DIY and was easy to open at the time).

When I came back one week later I found the room had an awful smell and 4 of my female foai had jumped out of the tank and dried on the floor. :x

Since then, I tried to get more females back onto the tank but couldn't find any more at my LFS, so I waited.

During this time, the 2 males were maturing pretty quickly (population was then 2M/2F) and so it appeared that the smaller female was getting kicked out from one side of the tank to the other by either one of the male or the dominant female.

This female got popeye but was acting as usual, even while it was getting chased out a lot ().

I recently decided to add a school of Cyps to mild aggression on this female. I got 25 last week and the situation is now much nicer, as she doesn't get chased around anymore.

About 2 days ago, this female spawned with the dominant male, though she appear to have lost the eggs today (still quite young).

Now to the real question (sorry for the very long start): What should i do ? I'm not sure when it actually appeared, but this female now has a air (or other gas) inside it's eye, and i'm wondering whether I should treat the tank or leave it that way. I once had a fish catch popeye (big one) but it recovered pretty fast without me doing anything.

I also think i recall reading somewhere that the bubble in the eye could be cause by a important amount of dissolved gas in the water and I have a wet/dry filter with a sump with an additional pump inside just for water aeration.

Btw, dunno if that matters, but I'm not using my lights anymore since about 2 weeks, so the tank is not as bright as before too.

For the complete picture, the tank is 200x50x60cm (6' 150g) and currently houses 2 N. calvus, 5 N. buescheri, 25 C. leptosoma and 4 C. foai. Water is 25°C with 0 Ammonia, 0 Nitrites and 20 Nitrates (my tap water is 15-20 :( ). It's been set up 1.5 years ago and the foai were added 9 months ago.

Thanks in advance for any input. :)

PS: side question, do you say it or he/she when talking about fish/pets ?

Vincent, what is your normal tank maintenance routine on the tank?

Eye issues can stem from a couple of different things...Poor water quality is usually top of the list, followed by injury, or bacterial infection (which can be caused by poor water quality or injury).

I would do some daily water changes, and treat the tank with Melafix for now. Should the fish stop eating or develop any other symptoms, you may need to treat with antibiotics.

I'm doing 25% weekly, sometimes twice when i have time.

Okay, I will treat the tank with some product (don't know whether i will be able to find melafix here in belgium).

Is the bubble in the eye susceptible to disappear with time ?

What kind of test kits are you using? Are they the test strips that you dip in the water or the liquid reagent kits? How long have you had them?

Since this has happened with more than one fish, I'm still suspecting water quality. I would get a second opinion on my test results, and start doing some frequent water changes in between.

Yes, it can resolve, but you'll have to get to the root of the problem, first.

Liquid reagent, for "about" a year. :-? Yeah, I know it's time for to renew them again.

Only one fish has this problem. Did I say the contrary ? If so 'Oops'. :D

Sure. I'm thinking of aggression first since all fish seem to be in top condition and behave like they have the time of their lives. :lol: Seriously though, I know I should quickly get a new test kit but I've been busy lately and well, since I'm doing what I considered to be a very strict tank maintenance, i got lazy. :roll:

I also forgot to note that the pH is 8.4.
