Got a spot of algae, originally was suppose to purchase some Amano shrimps but when my LFS received a new batch they looked too small to be introduced into my tank as I though the mouthbrooders would see them as food, also informed if no algae present the would start eating the plants. LFS suggested a baby Bristlenose and due to them being very small (an inch in size if that) would be idea as they would beable to clean up my plant leaves. Once in the tank I thought I was having double vision on inspection I saw him/her at one end of the tank but hold on how did he reach clear over to the other side of the tank. To my surprise I found out through error by LFS I have two. My research :read: has been some what limited but as far as I am aware catfish/Plec are unsocialbe when it come to mixing with there own kind. At what size do I have to think about rehousing one, considering their both juverniles will they grow to live with each other. At present there in a 20 gal long tank, and doing a wonderful job of eating all the algae in sight. I've also be reasured that a bristlenose will not grow any bigger that 4" is this correct?? made that mistake the first time around some years ago and brought a plec around the same size and though what a cute little thing(how niave was I) What I had aquired was a baby Common plec that inherited the name Monster after about 6 months as it grew to a 1ft in length making me purchase a 5" tank when it grew to just under 2ft I decided that it was time to find him a new home.
