Fuzzynicki mine turned up this morning and i had no idea they were this small either having never seen them in person they are very fast though and are in with my male betta but he is constantly trying to eat them!

wish i could afford another nano just for these guys and loads of moss! There was 8 when i went to work and now i have only seen two

i made a hole in my moss ball for them to hide in though and i know at least one is in there!
Edit: forgot to say brilliant communication from seller really happy with everything! Cheers, matt
