Hello, I come to you with a rather strange predicament. My 55g aquarium has been up and running for 2 months now, everyone seems happy, everyone is eating, etc. I perform 10% water changes 2-3 times a week, I change filter pads when necessary, etc. My water params. are ammonia - 0ppm, nitrate - 20ppm, nitrite - 0 ppm, GH - 25, KH - 120, pH - 7.8, temp - 81 degrees farenheit. I'm running a rena xp3 and emperor 400 filter, and my current inhabitants are 3 clown loaches (3" each), 2 opaline gouramis (3.5" each), 1 cae (4.5"), 1 pictus catfish (6"), 1 eclipse catfish (7"), and 1 needle nose gar (6"). (and yes, I realize that this is too much for this tank size... they are all still quite young, but I am searching for an adequate home for the eclipse catfish. If you're in the LA area and are interested, let me know and we might be able to set something up.) My question to you all involves my needle nose gar. (hence the title) I purchased it approx. 2 weeks ago, and it has been eating very well, usually on the order of 2-3 small comet goldfish per day. It has been mildly skittish when I walk by the tank, but otherwise has no peculiar behavior. As I was performing a water change this afternoon, I got a good look at the needle nose gar from the top, and I noticed that it has several swolen areas under its skin. I did not count the number of them, but I would say there were approx. 6-8. They are not that large, but came as quite a shock. I have no idea if they might be tumors or not, I've checked around on the internet and have not been able to find something that looks similar. The easiest way to describe it would be like a fairly large pimple that is rather deep under the skin. The top of the fish is semi-translucent, but these lumps are not. I have to leave for work in 10-15 minutes, but if anyone is able to offer any advice I would greatly appreciate it. One last note, I have isolated him in my 10g iso tank, just in case whatever is wrong with it is contagious. (and I've given the other fish a quick once over and did not notice the same problem on any of them) It does not look anything like ich, but hey, if that's what you think it might be, by all means, please speak your mind. (and yes, although I know my tank is a bit overstocked, feel free to point that out and even make suggestions if you like, I am always open to new and different opinions)
