Pale Fish is not eating

[mervkdustbust]

Hello,

I have a pale fish that is not eating. He is a male show guppy about a cm long in a 10 gallon tank with three other male show guppies . When we first got him (about two weeks ago), he was bright yellow, but he is now a very pale yellow and doesn't eat when we feed him.

Any suggestions?

Thank You!

Hello Merv...

It's difficult to maintain a steady water chemistry in a small tank. Just the waste material from a few small fish can change it. Changes in the water never works out very well for the fish. What's your water change routine?
