I don't know your level of knowledge, so my comments may be well known. Shoaling fish that are maintained in small numbers will become more aggressive because of this. Many factors affect this obviously, but the nippiness which is probably natural for the species is almost certainly to be increased with so few of them. I think both of these species should have more in their group.
I have to admit, I stupidly went on the advice of the aquarium I was buying from, who said that the 'dwarf green rasboras' (which is what they were calling the Sundadanio Axelrodi) did well as long as there were at least 5 of them. I will buy a few more and see if that settles them down - I guess I just have to try to make it work at this stage.
The CPDs seem like they're doing well - they eat well, they're out of the vegetation most of the time and their colour is improving every day. I think I'll just leave them in a group of 5 and keep an eye on things.
The most troubling thing is that my shrimp keep dying. I've lost 4 so far, after the cycling of the tank was complete. Water parameters have been completely stable during this time (Ammonia: 0, Nitrites: 0, Nitrates never going above about 5ppm and PH about 6.5) and I have no idea what is wrong. I have one little washed-out male left. Any advice?
