This is bad!

  • We are currently upgrading MFK. thanks! -neo
I took another look today and now I'm not sure what it is. It didn't seem as bulgy as it did yesterday. I hope it's just a sore.

I understand that if it is a tumor it might have spread. That's why I've also been looking at the rest of his body to see if there are any others.

Right now the SG is around 1.004 or so. I was trying to get it up higher. I'm amazed that you had one live in freshwater for 8 years. That's gotta be some kind of record. If it's not the salinity of the water, could it be things like nitrates? There are a lot of guppies in there and it's hard to keep up.
I wish I knew what this was. At least if I knew it was a tumor I could put his driftwood back in so he could hide.
Oh and, Pufferpunk, whatever this is isn't pinkish at all. It's red like blood. I'll try to get a picture so you can tell me if it resembles what your goby had.
 
Definately try to raise the salinity.

Also, get the water tested and let us know the Nitrite, pH and ammonia.
 
that sucks!!! srry to hear about your fish! good luck treating him!!!
 
I had an idea lastnight. Do you guys think it would help if I quickly set up my new 210 gallon tank for Ying (the violet goby)? I wouldn't fill it all the way up. Sand from his current tank would be placed in there to help it cycle, as well as the sponge filter. I could keep track of how much water I put in there so I know how much to medicate. At least in the new tank he'd be in an environment with a much smaller bioload, which I think would help.
 
I think I found the cause. The nitrates are WAY too high and the pH is too low. I did a water change and tested the water, and the results weren't much better. So, I'm going to do another water change.

Does anyone have anything to say about setting up the new tank?
 
My vote would be to leave him in the tank hes familiar with and avoid the stress of the move and possibilty of ammonia problems with the unestablished tank. Thats just my $0.02 though. Really hope he gets better man
 
I did a third water change, and although the nitrates are still too high and the pH is too low, it is improving.

Meanwhile, the "tumor" does not appear to have gotten better or worse. Hopefully when conditions are better, Ying's immune system can beat it.
