So, the other day my shrimp died.. I don't exactly know why, he was untouched just curled up on the bottom of the tank.
I decided to get a new shrimp, this time one called a Chameleon Shrimp. It is a male and has rather large claws. The girl said he'd be fine in my tank etc. Anyway, today when I came home almost all of my Betta's tail fins were gone, (not the front, or bottoms the tops and backs).
I immediately secluded my new shrimp, convinced he was the wrong doer, but then I looked at my filter.. I had cleaned the tank just before I put the shrimp in and I had accidentally put the sponge up a little high and a few cm of filter was showing. I also put the filter on high because I stirred up a little stuff that I wanted to get rid of.
The amount of damage that was done to his fins was extensive, I have a hard time thinking the shrimp is responsible now, plus i've seen the shrimp try to nip at him if he gets to close but my Betta swims away fast.
Any thoughts? What does the damage from a filter look like? I have a 5 gallon tank.
