As many of you saw in my redorated betta tanks, i have some little hamster tubing in my betta tanks. all my bettas LOVE these tubes and know how to go in and out with ease. several of them "sleep" in them or rest in there when lights out.
Well my gold fish love to go inside the little collusium that is in their tank, (well the smaller ones who fit in there anyway). so i thought they might like the hamster tubes too!
i had a couple of extras, so i put them in with the goldfish.
the first few days nothing
then some of the goldfish found their way in there, foraging for food flakes....
they get in there and then try to swim UP, instead of OUT. you see this little panicked look on their face when they can't get out and they flutter back and forth and back and forth until they FINALLY figure out how to get out.
they definately don't like them as they cant figure out how to get in and out, so i'm gonna take the out and not strain their little brains any more.
this was never an issue with the bettas as they figured them out in seconds.
there you have it....bettas are smarter than goldfish!
