dmed: regarding how that happended, I bought two thinking they would be about the size of silver dollars. Then after I learned how big they would get, about a year ago, I bought them a 75 gallon tank off some guy on craigs list. He was moving and couldn't find a home for his 12 inch pleco, so I offered to take him. After about 3 weeks with the tank up and running it leaked. All over my upstairs. Needless to say my husband was livid. I had to quickly pack all 3 fish back in the 35 and plead, beg, etc for my husband to get over it so we could put them in something bigger. Its a long story, don't get me wrong, I adore fred, but if I had it to do over I don't think I would have gotten him.
