i couldnt even see a beta in a small bowl without a filter ......... on the ***** container it comes in , it says , betas are very happy in this container and in nature the live in small puddles in rice field .......!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 ok This is why i see half of the betas dead in the containers at ***** ............... so if they live in small puddles in the wild , does that mean they should take the same abuse from a pet owner ,,,,,,,,, SETUP A FREAKIN 10 GALLON TANK FOR THE FISH THAT DEPENDS ON YOU IT WILL MAKE IT THAT MUCH HAPPIER AND FOR PETE SAKE GIVE IT SOME FLOWING WATER
