Just a quick little update, the achilles seems to be doing better today. When I got home from work, I went straight down stairs to the tank. When I got around the corner I noticed him right away, because he was black again. YAY. Now he does still have a little bit of ick, but he is still eating a ton and has a big gut on him. Here's a couple pics I just took.
Here he is picking algea off the bottom of the tank.
Here he is with his new little buddy, our new Sargassum Trigger.
About the trigger, I just picked him up from Aquatics Addictions on Wednesday. I am thinking that maybe he is somehow making the achilles feel more comfortable now that he is the new guy in the tank. I don't really know, I am just happy that they are both eating and the achilles seems to be on the right track again.
