I added a small pleco to my 10 gallon tank on Sunday, and he died within 24 hours. I have had no problems with my tank recently, all fish are healthy and have been living for a long time. I had a spotted algae eater that grew so large in 3 months that I had to return him and get a smaller variety. This is my first experience with this pleco, which I think they referred to as a Chinese pleco. Are these typically very sensitive? Any ideas why mine died so quickly? Thanks.
