Upset fish new tank

Genevieve82 · Dec 1, 2016

Hi Genevieve here.
I bought a ttopical fish tank off a friend and aquired 3 fish with it.

Unfortunately one of the fish has a scabby eye and I would like to treat it if possible.

Hoping someone can give me some friendly useful advice.

Thank you.

Hi there, welcome to TFF

It's a little difficult to see what might be wrong from that picture, so I'm going to have to bombard you with questions before we can help; sorry in advance!

Do you know what kinds of fish you have (this one is an angel fish, but are the others?)

How big is their tank? Have you tested the water at all? Do you know if your water is hard or soft? When was the last water change, and how much water do you usually change? Do you remember to warm and dechlorinate the new water before you add it? Has the filter, or anything inside it, been replaced or cleaned in tap water?

The reason for all those questions is that a lot of fish health problems are caused by something in the environment.

Do you have any idea how long the fish's eye has been like this? Does it look red, yellow or white and is it fluffy?

Again, I'm so sorry to have to flood you with questions!

Fresh water on Monday when I got it. treated water with something I got from pet shop to get all the crap out of it.

Have a sucker fish and one other that I have no idea on.

Looked at pictures and think it might be cloudy eye?

thanks

That eye is indeed quite funky looking. Almost all eye problems stem from poor water quality, resulting in either a bacterial or fungal infection. Did the fish get the eye problem soon after you acquired it? It's possible that the change in water parameters (pH, hardness etc) from your water supply and the other owner's water was too drastic for the fish. I would test both yours and the past owner's water and compare the results.
If it's not a change with the water, I say when in doubt, do a water change. If my fish start behaving oddly or having problems, I do more water changes until things settle down.
I would address the water issue first, then quarantine the fish in a separate tank, preferably something around 10 gallons. Keep in mind that the quarantine tank has to have its own heater and filter. I've used Tetra Life Guard to cure eye problems in African cichlids, but the fish still lost its sight in the infected eye. He's adapted over time with one eye and still eats and holds his own with the other cichlids.
