Please forgive my long post, but I want to give as much detail as possible to anyone who can help me.
Here is my situation:
I have 7 Shubunkins, 1 Sarassa Commet, and a regular common gold fish that I recently transferred from a small tank to a 29 gallon tank. They average about 3 inches with the smallest being about 2 inches and the largest 4.
I transferred all the fish a few at a time over the course of a week, and this was with the aid of Bio-spira and some gravel from their previous established tank. The tank has a good amount of plants, and filtration is provided by an Aqua-tech 20-40 AND a Penguin 150. Up until a few days ago, I was running a long airstone in a back corner and two buried small air stones at opposing corners trickling air (via gang valves). The PH is 7.2, Amonia level 0, and the temperature averages 76-77 with a heater-less setup (I'm in Florida).
The last one transferred this past Saturday, and all of them seem happy and active, but a few nights back I noticed that their eyes seemed to be bulging slightly; it's most noticeable on the 4-incher.
I did some research and while Bacterial infection may be possible, Gas Bubble Disease seems more probable (to my uneducated mind). When I read about GBD, the saturation of tiny bubbles flowing around the tank seemed less harmless to me. I've disconnected the air pump and the Penguin 150 (the Bio wheel is sitting in a cup full of fish tank water)
Since then, the eye bulging doesn't seem any better. To my increasingly paranoid mind it seems worse.
If this is Gas Bubble Disease is there anything I can do??
As I mentioned before, the fish seem happy and active with no drop in their appetite, nor any clamping of their fins. Still, there is no denying (in my mind anyways) that the bulging eyes is a sign of trouble.
I will be purchasing some medicated food in case this is a bacterial infection.
Again, sorry for the long post. Any advice, help would be immensely appreciated. I have a very sentimental attachment to these guys as they are about the same age of my baby boy and I envisioned them being around with the family as he grows.
Thanks,
Gimpy
