Hello.... I read a few messages today regarding common plecos. I have one in my tank and have noticed him picking on my goldfish. Tomorrow he is going to a new home (a co-workers tropical 150 gallon tank). He is about 6 inches all ready and will probably grow quite well over there. Anyways, what is the difference in behavior for the other recommended plecos listed on this site? Isnt a pleco a pleco regardless of what kind it is? Please inform.... Also, I saw the dojo loach recommended as well... I honestly had nothing but problems with my dojo and sold him back to the pet store. I now have my apple snail to do the job of the others, but would like to get another pleco if appropriate. Please advise.

Ok, so I forgot to mention one other thing.... What about the Chinese Hi Fin Banded Shark? I have heard mixed reviews about these guys... Please inform. Thanks!!!

Someone please inform! Thank you!!!!!!
