Panda Cory's dorsal fin's black color is fadding!

[gu2high]

I noticed one Panda Cory's dorsal fin's black color is fadding and I thought it is a unique case. But now I find others are also losting black color.

I am feeding them:

Wardley Shrimp Pellets Formula, but they do not like it very much.
TetraMin Tropical Tablets.
Hikari Algae Wafers
Maybe other foods in the bottom like flake, etc.

What kind of foods will bring the black color back?

What are your water parameters? Sometimes color loss is a result of stress. Any other physical signs of illness?

:O Anne, we are canadian, we are supposed to include a U in the word Colo(u)r with pride :P

Anyways, yes, fish will loose colour during stressful times. No food can cure stress.

Also, what size tank are they in, what is the tmeperature...

Water parameters are probably the most important thing, and we need those before we can help you further.

ROFL, I know the "U" is supposed to be there, sometimes I forget, LOL.

Three panda cories and three ottos and 40 platy and zebra danio fry in a 10 gallon tank. I do pwc (25%) every 2-3 days. pH7, temperature78, ammonia etc. are all zero. No fish bother the panda. I do see two panda are not dancing around as usual, but no sickness as I can tell.

Maybe I should provide more hiding spots for them if they feel stress.

The ottos are fat and happy, especially one of them is very fat with a very big belly.

how old are the pandas? sometimes fish begin to fade as they reach the end of their life cycle.

[gu2high]

They are small, between 2-3 cm, less than 1 inch.

hmm, then that is not full grown... How much oxygen is getting into the water, is there alot of surface disturbance?

I am not too sure about FW, but in SW, fish will loose color due to lack of a varied diet.....

[WaterPond]

same with FW, but the list of food gu2high should be enought variety for a cory cat

Isn't that a lot of fry with those other fish in a 10 gallon tank?

[gu2high]

The oxygen in the water should be ok as HOB gives lots of bubbles. It may be too much fry. However, the color is stopping fadding and I feel relieved. I plan to give all zebra danio fry to lfs as I have 7 of them in another tank. When platy fry get big enough, they will also be given away.

The next thing for me to breed is the Panda Cories. They are still too young so far.

i just bought 6 last week, i plan on 2 more, hoping to get them to breed too.

Glad to hear the color is not fading any longer. I still suspect some sort of stress was the culprit.
