Goldfish?

Tonight I finally decided to put the light back on the top of our aquarium. I had left it off during the summer so "the girls" could sit and watch Fester swim around underneath them. After watching him a while, I just wonder...can they see theirselves in the glass? I mean...looking thru the front of the tank, it looks like a mirror to me, but does it look that way to him??

Yes. Yes, they do see themselves. They are arrogant, so they like it.


Just kidding. I don't know. Interesting question, though. I wonder. I know that if you hold a mirror up to a betta fish in a bowl, it attacks.

My! You are feeling froggy tonight, aren't ya? Thing is....I can peer thru the tank from looking in the top, but I can see out....but if I look thru the front, it looks mirrored. If I could just fit in the tank with the lid and light on...I'd know for sure!!

Well I know if you hold a mirror up to a betta, it will "attack" its reflection, so I would imagine just about any fish can see themselves.

I'm pretty sure they can, unless goldfish eyes aren't as good as betta eyes...My recently deceased betta used to wear himself ragged, flaring at his reflection in the tank glass. =3 My new bot in that tank doesn't particularly care for flaring at himself; he doesn't even flare at himself in the mirror! But then, he flares a lot of the female betta sharing his tank (it is divided, of course).
