How Far Can A Betta See?

[fourthtimelucky]

Last night I noticed a little fly buzzing around (I think it came out of new houseplant next to the tank) and so did Mr Fantastic he was dashing up and down trying to get at it whenever it came within an inch or so of the tank. Today I noticed that when the cat was rolling around on the floor he did a little flare and a dance at her, like he was joining in (or, less anthromorphically, warning her to keep away!)

I have a friend who has a red vt male and she can't put anything red next to / in the tank at all because he constantly attacks it. He doesn't respond to other colours in the same way.

So I guess they can see quite a way out of the tank into the room, follow movement and distinguish between colours.

Does anyone know what betta eyesight is really like? Do they see the same colour spectrum as us? I'd be interested to know.

I've read that they can see up to 60cm....which is pretty cool, mine watches me when i am within reach outside the edge of the tank.....also my tank is fairly close to my tv and all the fish often go that side of the tank and sit in wonder at the light of the tv

Wow... I think mine reacts to the TV as well but thats further away than 60cm... but I guess he sees the light flickering if not the picture. Interesting.

yeah i expect 60cm is the furthest they can see with focus....they can probably sort of see things further away but like you said.....the changes in dark and light....and i suppose colour....
