Ok well im in the very very early stages of just planning a coral cat shark tank..i have decided to go with a 225 gallon tank which is reasonable for me to keep in upkeep prices and also i believe is a good size for one of these beautiful creatures...im now thinking about how i want the rockwork to give him caves to stay in and i think im going with a huge cave structure that my lfs got for their bamboo...and now im thinking about future tankmates..ive been reading that triggers, puffers and the large angels arent good tank mates...so what would u guys keep with a coral? i probably wont be putting the tank into cycling for months so i have lots of time to think if i wnana get a larger tank, or if im even prepared to under take a care of a shark for the long term..i mean i think the biggest mistake in the hobby is that one day the fish is cool and then r u rdy to take care of it for 5 years? 10 years? etc...and i never had an aggressive tank either...im a reefer soo these things r all new 2 me..
