Mottled Glowlight Tetra

[fizzlesticks]

Hi there,

I could use some help! One of my glowlights is looking very strange--it looks like there are white marks or lumps inside the fish.

Tank size: 30 L
pH: 7.4
ammonia: 0
nitrite: 0
nitrate: <5ppm (using API liquid test kit)
tank temp: 26 degrees C

Fish Symptoms (include full description including lesion, color, location, fish behavior): One of six glowlights appears to have white lesions inside it. It's not misshapen in any way. It is moving and eating normally. None of the others have any signs of ill health. These marks appeared in the last couple of weeks. If they weren't see-through fish I don't think I would have spotted the marks!

Volume and Frequency of water changes: 25% weekly

Chemical Additives or Media in your tank: Using Melafix. Filter has sponge and Seachem Matrix.

The tank's been established for about six months now. I recently added a few new plants, but that's about it.

I'm in Australia, if that helps. I tried to take some photos on my iPhone, but they're all too blurry--damned quick little fish!

Any thoughts?

I've had a similar problem with some of my tetras; I used Myxazin and it cleared up with no problems.

Thanks--I'll check that one out. Would it kill the bacterial filter?

No, it won't

Thanks! I've ordered some.

I ordered the meds yesterday and then today the lesions are gone! Gosh, that Myxazin works quickly...it hasn't even arrived yet! I guess it will come in handy in the future.
