I'm building a 540 gallon tank for my eels and was wondering if I would be able to get a bamboo cat shark. I have a green moray(22"), specked moray(22"), yellow head moray(24") and a snowflake eel(15"). The tank will be 6'x6'x27". And yes I know the green moray gets huge and if I get anything else for this 540 he won't be able to stay for life. Once he gets big I plan on building another big tank just for him. I will also want to get some other tankmates for them but don't know what. So any suggestions would be great.
