Hello, I have recently bought an Albino BN Pleco. He’s about an inch right now. I tried putting him in my 40 gallon tank with a Rubber Pleco, but the Rubber bullies him. I then transferred him to my 5 gallon tank that I usually use to quarantine small fish, but there is nothing in there currently. It has a filter and a heater. He seems to be doing fine and he has a big appetite. He has recently grown two little bristles on top of his head and they look like little horns, although he’s the same size when I got him a few weeks ago. Is his growth being stunted and will I have to buy a bigger tank for him? Thanks. I have added an of him.
