hi, guys im new, and all my fish are healthy and eating, but ive noticed that the bigger of my 2 zebras sometimes swimms on the edge of the glass almost like he sees something out their? concerns, comments?
Gobies do that. Mine will try to show his dominance to his reflection to protect his territory. And he will teas my cat. The only concern would be that you have a large bio load in your 29 gal tank and your gobies and clowns may be having a territory dispute.
