puffer help

[akakabuto]

I got 2 amazon puffers in a 20 gallon today. They are not eating and won't stop swimming up and down the glass chasing their reflections.

Any answers why they follow their reflections?

2 reason they would chase their reflections...
-HORNY, yeah your fish want some
-ANGRY, they want to kill their reflection

Turn off the tank lights and only have the room light on that removes their reflecton well.

My fahaka puffer did that for awhile after I got him into his new home. He got over and lost interest in the reflection. I read that they call this "glass surfing".

Very typical for this species. They are very hyper/nervous-types. Tons of decor may stop the pacing. Are you aware that this species needs it's teeth hand-trimmed every 4-6 months?
