I recently purchased a hammer coral from my LFS and after the first two days it is looking amazing and everyone in my family says it is their favorite coral. Sorry, but I have a question about hammers while we are on the subject. How much space is required between the hammer and the other corals? HTH
I also love frogspawn! It's the least aggressive in the group (torch, hammer, frogspawn) i believe and will not form sweeper tentacles. That's what my LFS told me and my frogspawn has never seen to have any sweeper tentacles. Its look is also very amazing
I'm one of those fishnutz, who are actually nutz.
A good way to find out about sweepers is to check the tank after the lights are out for a few hours, a few days in a row. I have had torch corals that didn't sweep for 3 or four days and then BAM, it was sweeping 6 inches all arround it one night.
VERY IMPORTANT - if you change your powerhead/current arrangement in your tank, think about how this changed water flow is going to affect your coral's sweeper action. I have made this mistake before, and got a leather that was safe before all stung to heck.
