Alright, while I'm waiting for my first tank to cycle (120 some litres, maybe 32 gallons?) I've been planning on how to stock it. I love the look of tiger barbs but was at first discouraged by reading how they did not get on well with other fish as I wanted more than one type for my first tank. Reading on, I heard how RTBS (red tailed black shark) can get on well with tiger barbs and since I don't mind the look of RTBS either, I figured that would be great. My tank is 30in long so the RTBS should be good from what I have read. With a school of tiger barbs and with the RTBS I'm getting pretty closed to being stocked I think, right? So here's the questions: With just a RTBS besides the tiger barbs, how many tiger barbs could there be? I'm thinking 8-10, but input would be great. If I kept the tiger barb school smaller (5-6, say) are there any other fish that would be able to handle themselves in this tank? In particular I am curious about different tetras (neon, serpae, skirt, bloodfin) or a pearl gourami. I am aware of the agressive nature of the tiger barbs so suggest any that could do well in this tank. Is there not enough room?
