Any reef tank can cause anxiety when it comes to vacation time and leaving them in the hands of a sitter. Seahorse tanks can even present more challenges than the usual ones since they need lots of food but also excellant water quality. I am lucky to have a knowledgable sister willing to help me out. I will be on a 2 week vacation coming up and thats the longest I have ever left the ponies. There are lots of preparations to be made from ordering live shrimp to making a brute can of pre-mixed salt water. Hopefully the best laid plans pan out!
