Red eye tetra - very skinny

[labidis]

One of My red eye tetras seems to have lost its appetite.
It tries to eat but spits the food back out.
It has lost heaps of weight and shape and doesnt want to swim much, and is no longer hanging around his school. His fins seem to be deteriorating too.


tank parameters (ammonia 0, nitrites 0, nitrates 5, temp 26, pH 7.0


tank size is 33galon or 125ltr?
the tank has been set up for 8 months?


4~What type of filtration is aquatopia 650ltr/hr


5~ there are currenlty a total of 34 fish in the tank.
Approx sizes are


1 x Rainbow Shark: 10cm
1 x Guppy blue male: 3cm
1 x Guppy Yellow male: 3cm
1 x Guppy Orange male: 3cm
1 x Guppy Black/Blue male: 3cm
1 x Guppy Orange/white female: 3cm
5 x Red eye tetra: 3.0cm
1 x Platys female: 4cm
4 x Platys male: 2cm
10 x neon terta: 2cm
2 x pink widow: 3cm
6 x white clouds: 2cm

I perform water changes every 10 days at 50%.
It was last done 7 days afo


I have had the red eye tetra for about 6 months


I have added a fully grown anubias plant and driftwood about 7 days ago and also started using API CO2 booster 7 days ago.
Also added some rock to bring up the hardness and ph a few weeks ago

I have fed the fish the same food the whole time which is tropical flakes.
I did however feed the fish some live shrimp 2 weeks ago for the first time.

You really shouldnt have so many tetras along with the guppies in that size of tank. I would say pick one or the other, that is way to much and besides tetras like soft water while guppies like hard, ect ect.
If you see your guppies bellies get fat and then stringy poo and then look emancipated (skinny) it could be signs of Heximata aka Hole in the head, but at this point i would just remove the sick fish and keep an eye on the others, if it does get out of hand the medicine to use would be Metronidazole 1 heaping measure per ten gallon every other day for at least a week.

Okay, thanks for that info matt.

The red eye died a few days ago, after i had taken it out if the tank.

I have since noticed some stringy poo on some of the fish... Will monitor and take ur advice on board regarding medication.

Thanks again !
