Need Help With My Rainbow Shark Fish...

[Up.side.down_fins]

Hello Guys, i'm new to the forum but i saw some the post looking answers for my apparently ill fish. Anyhow...

I have a fish tank with 50 liters and many inhabitants

3 nuns
2 tiger barbs
2 swordtail
1 platy
1 snail
1 plecostomus
1 rosy barb
1 gourami
1 goupy
1 rainbow shark
1 catfish
1 angel

Tank Info:
pH: 7.5
Temp: 26ºc
nitrite: n/a
ammonia: unknown
airation: good
waterfall filter
thermostate

My rainbow shark, which i bought a few weeks ago, got used to the fish tank very well and without any problem, but recently i saw him moving around normally but when he moves i noticed it's mouth white, kind of fluffy, for what i know that is cotton mouth.
At first i thought he had a flake stuck in its mouth, but it has been going on for a few days. it swims normally, no whitespots, doesn't hide much. One fact is that he usually "plays" with the gravel on the bottom of my tank.

Hope u guys can help me with advice. Thank you.

wow alot of fish for a smallish tank and some grow big too which will need rehoming pledo(depending what species it is) catfish and rainbow shark (but they grow fiarly slow apparently)

sounds like cotton mouth to me too you will need to give it some meds ( someone else maybe better at pointing you in the right direction for that)

as for the pics you need a site like photo bucket to uplaod your pics to and then copy the img code and paste it on the post that you have wrote or replying to

hope this helps you in someway

Most of the fish you have need to be in groups of 4-6.

Yay! I managed to upload the pic of my fish to the post, hope it useful for the advice.

I know that some fish nned to be in group, but since im kinda new into this hobbie i thought it would be nice to have em lke that, but i will try to accomodate them better.

Thanx for the advice so far.

I would just take it back to the shop you bought it from.

Read this about them and you will realize why you should get rid of it.

50L is 14G as a newcomer to the hobby you should aim for around 14inches of fish

3 nuns ? neons? - 3"
2 tiger barbs - 3"
2 swordtail - 4"
1 platy - 1."
1 snail 1"
1 rosy barb - 4"
1 gourami - 4"
1 goupy - 1"
1 catfish what type? corydoras?? 2"

23" in a 14G without even including the 3 big boys show below

1 angel 8" needs minimum of a 100L
1 plecostomus 12-18" common sp. need 300L +
1 rainbow shark - 6" needs 200L+
