As I was getting ready for work this morning, I turned on the tank lights to "wake up" the fish before feeding. I have a very pregnant
Guppy that's been hugging the substrate for the last couple of days, and I was looking to check on her.
In the area that she's been holding, I noticed something white off to the side of the tank. At first glance, it looked like a moult from a ghost shrimp, but I have none in my tank.
Upon closer examination, it was the complete skeleton of what turned out to be one of my white cloud minnows. There was not one fragment of skin, meat, or anything on this skeleton. It had been stripped clean.
What could have happened? I had done a 25% water change earlier in the evening, and did not have any dead fish. My tank occupants are guppies, long-finned leopard danios, white cloud minnows, spotted cories, 2 clown plecos, 2 ottos, and 1 blue mystery snail.
Which of these should I put the blame to?
Any ideas or suggestions would be great.
Thanks.
