Not sure about axelrod rasbora, but I keep
- Boraras brigittae (AKA chili rasboras or mosquito rasboras)
- Boraras urophthalmoides (AKA least rasbora or exclamation point rasbora)
in my shrimp tanks and I love them!
They definitely shoal, but also aren't too shy. They are wonderful little fish to watch in a smaller tank. I only bought them as a small fish to try to keep down the numbers of micro-fauna in my shrimp tanks, but now they're my favourite fish I think, especially now they're maturing slightly and are colouring up. Need to give some thought to feeding though as they have very small mouths (hence why pretty safe for a shrimp tank). My bigger fish can eat the Dr Bassler M-size food I have (0.5-0.8mm pellets according to the label), but the smaller fish struggled getting these down. Actually they all prefer the shrimp food, especially the Glas Garten
Shrimp Baby powder, which makes life easier. Oh and they love chasing freshly hatched brine shrimp of course!
