Hi, I am a newbie and could really do with some info on why my axie keeps head butting the end of the tank. I have 2 in a 60lt tank, both are eating well, and tests show that the water is fine, temp is also ok. They are both about 16cm long, could my tank be too small? Only 1 is doing the headbutting but both like doing laps. He/she (not sure yet)doesn't seem to get hurt, but acts surprised when it happens. is this strange behaviour normal?
