Was sold to me as Mosquitos. I've googled them and there are photos that don't match
These are only bout 1.5cms at most. So they colour up when adult? They are actually a little pink at the moment. They didn't have any colour in shop
They were in pet shop for over a month. They had them in a tank in the store room out back. Found they couldn't put them in their normal tanks in shop due to size.
No plants in there tank, and almost over crowded with guppies and platties. I'm guessing the rasboras didn't like that.
Looks more like Boraras merah to me. There seems to be a bit of confusion on the application of common names to species in this genus. Chili/mosquito rasbora seems to be applied to bth B. merah (which is the one you appear to have) and B. brigittae (which is the one Meashkah seems to have). That would account for the difference in the intensity of red coloration. Do an image search on the two species to see what I mean.
