More bad luck.
Lawnmower blenny died. It was VERY thin and despite trying to tempt it with algae, grazer's discs, and all sorts of food it just wouldn't eat. I honestly don't know what was wrong with it, because I had it fed in the LFS and it did eat some brine shrimp, while in my tank I saw it desperately trying to graze off the glass.
However much I like these fish I don't think I will get another.
Last Thursday evening the female herald's angel died. I found it convulsing at the surface of the tank. I set up the hospital tank but to no avail, it died in the night. I'd had it for less than a week, so the LFS is going to replace her for free, especially because they know me and how I keep my tank, so they agreed there must have been something wrong with the fish to start with.
This morning I found out that the sixline wrasse had decided to go carpet surfing. I found him behind the skimmer all shriveled up.
... and lastly, my male herald's angel, this evening I have found with a swollen right side, a bit pale on the swelling and the right fin ruined. Again, transferred him in the hospital tank, with a dose of penicillin.
To be honest I am quite hopeful in his case. He doesn't seem particularly stressed by the injury (because I do suspect it is an injury), and he did try to put up a fight when I went to net him. He's now swimming peacefully around the hospital tank. He's obviously having some difficulty, I'm guessing his right side must be quite sore, but apart from trying not to use his right fin he seems to be ok. If he makes through the night (and I have no reason to doubt he will) he'll be well on the way to recovery.
