most regrets were fish like damsels or a clarkii clown that hunts down other clowns and kills them.i regret some corals such as a carnation coral which any coral salemans that says you can keep them alive is flat out lying,they can't be kept alive in captivity,or a colt that had hydroids on it and was stung to death,zoos that had zoo eatting nudibranch.i regret using a 29 gallon high tank for a sump cause its to tall to reach into while its in my stand.i regret wasting money on a powersweeper rotating powerhead.it stops rotating all the time and heats the water alot.i regret 2 finnex titanium heaters that both stopped working within a week of the warranty expiring.i regret my short experience with led lights,waste of time.i regret owning a few of the sps corals i owned cause they were tougher to keep healthy than the lps and softy corals.
