Hey! so i have two male VT's. they are both in individual side-by-side tanks. the tanks do not have tops to them, they are open at the top. i have a few friends with bettas and they say that when they go to feed them, the bettas jump. i've also read on these forums that the fish jump...should i be worried that they can jump out of the tanks? because jumping is awesome, but i also dont want to put a top on the tanks. i left around 4.5 inches between the surface of the water and the top of the tanks, so i think that'll be fine, right? i doubt they can jump higher than 4.5 inches unless if they're amazingly agile ..
please let me know :)
