My brand new 4 slot divided tank is proving to be a nightmare! Here is my betta Rain after Goldy jumped the glass in-between them and obviously attacked Rains tail http://imgur.com/pQglx4K I was sitting at my desk on my computer and looked over to admire my boys and noticed Goldie swimming in the second compartment with Rain, i dont think ive ever moved so fast. What a disaster First question is, now his tail is badly ripped and has holes in it how do i care for him? I feel terrible for him. I have no idea how Goldy got through a gap of 1.5cm between the top of the glass divider and the glass lid! Im now terrified the others will do the same. I tried taking water out of the tank but then the air pipe was above water level, so i had to put the water back in. I now have no idea how to stop this from happening again. Please, dose anyone have any suggestions?
