My sun corals started off with about 6 heads. After a night feeding my 20in serpent ripped off a few getting the food away from it. Now that it has been in my planted tank it has grown from the few mangled heads that were left to around 20. I have always feed cyclopeeze and mysis, but tonight tried something different. Squid from the saltwater mulipack by San Fran. They got really intense after the feeding. Heads went from being dime sized to about the size if a quarter and the "stalkes" were as big as my pinky. 6 hours later they are still huge and seem to be thanking me for such a large protein boost. Try it! You will have happy dreams afterwards I promise. I am definitely incorporating this into my every other day feedings.
