@Gareth0508 add them gradually. otherwize it can cause a shock to your system. increase your bioload slowly and not to fast at once. the fish wont stress so much in that way and a smaller chance of sickness breaking out from stress. local fish are fine to add to your system. also the hermits and zoas. please when taking out zoas just take small frags from different pools. and not huge lumps. no matter how big the colony is.
Thanks The Fish
I have a few spots that I often dive and the colonies of Zoas that I've seen are massive!
Of course I wouldn't take a huge piece, just a few frags big enough to survive!
I still have a long way to go before adding any bioload to my system, so preparing myself with knowledge beforehand.
