Ok, my 4' community tank is getting on well, has a selection of zebra danios, black neon tetras, golden barbs, kribensis, khuli loaches and a plec. I am pretty certain my plec is a common plec, but is only 6" nose to tail. I have had him for around 4 years, having taken some fish from someone who was not looking after them properly and he hasnt grown more than an inch in this time and don't think he will grow any more. My reason for believing he is a common plec is because of the 14 or so rays. Anyway, I digress. I am approaching maximum stocking in this tank after some changes this week and looking for something more bottom loving as the khulis are a rare daytime sight! Im thinking shrimp and other loaches (maybe botia striata?) What are your suggestions?
