I think 20 Galaxy Rasboras is a tad OTT, but in all seriousness, what is there in nice brightly coloured micro-rasbora species that I could have 6-8 of?
If it's colour you want, then look into Chilli Rasbora. Although they are, as was said, very skittish.. their colours are fantastic, as well as this they are quite readily available in alot of LFS.
Quick question.. why would 20 Galaky look OTT ? The more of these type of fish you can have then the better they would look. My Chilli's CONSTANTLY live in and amongst my plants, they love cover in the same way a Dwarf Gourami would, but when they do all come together it's a beautiful thing (
