Oh no! Sick fish?! Come here and see if someone can help!

Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.

Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Knight goby w/exopthalmia... QT?

Post by CoreyK »

45g tank, Sg ~ 1.005
2 Figure 8's, 2 knight gobies
Ammonia: 0
Nitrite: 0
Nitrate: ~ 20ppm
Ph: 8.2

I noticed recently that one of my knight gobies has exopthalmia of one eye. It is severely bulging (looks like it is going to pop), the eye itself pointing upward with an apparent dark mass growing behind it, looks as though it may have a little blood in it as well. He appears to be blind out of it.
It's difficult to get a good look at it/picture because my tank has a lot of hiding, and the gobies hide pretty much 24/7.
The goby is acting normally, eating and hiding when he sees me. Coloration and temerament seems normal (he is still actively territorial and VERY fast).
Basically, he doesn't seem sick, just has a damaged eye.

I was gone for 2 days last weekend and noticed it when I came back (Monday evening). I performed a 25% water change immediately.

I know that there are various causes of such a condition, but wanted to get some opinions, both on what it could be, and what I should do about it.
The day before I left, I startled them pretty good by shifting the blinds near their tank at night, and I could hear several of them spazzing out, so him having physically damaging it is a possibility.
I'm concerned for the goby, and terrified that it will spread to others in the tank.

My predicament is this: I am at school and have no means for suitable QT, and I need to head home this weekend for several days again in order to set up the tank at home to bring all the fish home next week.
I'm afraid to leave the tank unsupervised with a sick fish, in case any other fish become affected or if the goby passes.
I could bring the goby home with me this weekend where I have a suitable QT tank, but it's not set up at all, ie. I would have to have him in a container while getting the tank running, the temperature and salinity right, etc. while he is already possibly immuno-compromised.

What should I do? Leave him in the tank at school and hope for the best, as it doesn't seem very serious at the moment? Or should I risk taking him home and QT'ing him, making him deal with the extra stress of travelling and being in a container for at least several hours, when it may well just be a physical injury?

Any input is appreciated,
Thanks.

Adding Melafix won't hurt anything & I've found it to clear up common pop-eye. Also, be sure you have pristine water conditions.
You are getting sleepy... you only hear the sound of my voice... you must do water changes... water changes... water changes... water changes...

Adding melafix is alright to add to my main tank? Ie. it won't disturb the bacteria?

If it was me I'd quarantine him anyway. Melafix doesn't disturb bacteria, but an enlarged eye says "pick on me!" to other fish in the tank. I had a molly with popeye once who had his eye mostly chewed off by his tankmates while I was away at school.
Tanks:
20-gal feeder breeder (platties and snails)
75-gal West African Lungfish + snails

Other pets: Pacific parrotlet, Italian Greyhound, lots of plants
