I had a vampire shrimp for a few years that past away. I kept him in a 29 g tank along with some rasboras, cories and a female bristlenose pleco. I decided that when he past I would move the remaining fish to my other tanks and eliminate that tank. I have two 37 gallon tanks and a 72 gallon tank. I want to move the bristlenose into either the 72 g tank but there is a network pleco in there, or the 37 g tank which has a male bristlenose. Whick would be a better choice? I have seen plecos fight in the past and sometimes to the death. Thanks.
