My glow tetra.

[muhaimin]

Hi everyone, my green glow tetra have been developing red lumps around it's head? What's the reason? Any treatment for it?

How long has it been like that?

It looks like a bacterial infection but if it has been that way for more than a few weeks, it's probably a tumour.

It's been like that for about 2 weeks. Any treatment I can do? Can it spread to other fishes?

How long did it take to appear and get to that size?

Has the brown bit grown during the last 2 weeks or has it been fairly stable in size?

First it was very mild, then just within a few days, it became like this. It did grow within these 2 weeks, but not like so much. The fish seems fine, swimming around, eating it's food. But I feel like day by day, the lump is slowly growing. It doesn't seem to get better.

If it hasn't spread to any other fish by now it's probably not going to.

You could try a broad spectrum fish medication (not an antibiotic) that treat bacteria and fungus. If that doesn't improve things after a week then I would say it's a tumour and there's nothing you can do.

If it is a tumour, you leave the fish until it can't swim properly or has trouble eating, then euthanise it.

Okay thanks for the info. When using the medication for the fish, must I quarantine it I separate tank or still keep with other fishes.

If you have a spare quarantine tank you can use that, otherwise just treat the main tank.

----------------------

Before you treat a tank, work out the volume of water in the tank:
measure length x width x height in cm.
divide by 1000.
= volume in litres.

When you measure the height, measure from the top of the substrate to the top of the water level.

If you have big rocks or driftwood in the tank, remove these before measuring the height of the water level so you get a more accurate water volume.

You can use a permanent marker to draw a line on the tank at the water level and put down how many litres are in the tank at that level.

There is a calculator/ converter in the "FishForum.net Calculator" under "Useful Links" at the bottom of this page that will let you convert litres to gallons if you need it.

Remove carbon from the filter before treating with chemicals or it will adsorb the medication and stop it working. You do not need to remove the carbon if you use salt.

Increase aeration/ surface turbulence when using medications because they reduce the oxygen level in the water.
