I hate giving updates about bad news, but I've had a few things happen in my oyster reef tank recently that I'm not happy about reporting. But, I have to tell it like it is.

First, my last skilletfish died. I had no idea it would happen. It was a hearty eater and full of energy every day. This was this past Friday.

Also, after fishing the skilletfish carcass out of the tank, I noticed that the female blenny, was being harassed by the males and was very stressed. She hadn't laid eggs in over a month now, and was extremely fat. I think she was eggbound. The males were still trying to get her to spawn, but, she wouldn't and avoided them. I think that all three of them were so worked up over her, that they wouldn't leave her be anywhere in the tank. So, I moved her out of the tank that night and put her into the tank with the stickleback. She immediately found a hiding spot in the oyster structure in that tank. I never saw her again until last night, when I spotted a mud crab feasting on her carcass. So, I fished her out.

While doing so, I noticed that the crab opened up her belly, and inside were thousands of eggs. At least my diagnosis was correct. But, that is no consolation. I loved that fish.

Also, the male blennies have removed all of the claws from all of the crabs in that tank. As I find the crabs, I try and move them to the other tank. Most disturbing was that they left the hermit crab alone all this time, until last night, when I saw his claws gone. So, I moved him out of the tank. The male blennies have killed mud crabs in the tank before and ate all of the grass shrimp. So much for that part of a clean up crew. I may keep only larger mud crabs in there from now on. The small ones will definitely get eaten if caught.

So now, I'm down to the three male blennies, and four naked gobies. Needless to say, I can't bring myself to post pics or videos right now, because this tank depresses me now. I'll have to revise my plan for the future with this tank to see if I can improve things. I have no idea if it was my fishkeeping that killed these fish, or, if it was just a natural progression of a combination of old age (skilletfish) and male blenny aggression. Maybe the larger tank will help. I'm working on that.

Blennies Rock!
