Is he in the mood?

Well my male clown was one of my best eater he is 400 grams and had no plugs but then he stoped eating. two weeks past then still nothing I checked for plugs and yes he had them did he stop eating because he is in breeding mode or what?

Could be. How old is he?

Are you planning on letting him breed?

Personally, I'd wait until he hits the 550-600 gram mark, but that's just me...

Well I had him for 8 months now when I got him he was around 150 grams
