I've had these Dwarf Neons for about 3 months now, and they're doing great!
Yes I forgot to include the Bosemanis on the fish list! (I'll update it now!). I have only 2 Bosemanis now as one died. I plan on getting 3 more but at £9 each, they aren't very cheap around here. They weren't quite as colourful as this in the shop, but I feed my fish TetraPro Colour and it seems to help
The disk tetras are a silver tetra, not dissimilar to a Silver Dollar, just with a longer body and a smaller size.
I don't know the scientific name as this is what they were labelled as in the shop, but they certainly aren't what you get when you google search for "Disk Tetra".
