Pristella maxillaris are Gregarious and non-aggressive. Quite hardy and should be kept in groups of 5 or more; minimum aquarium size 60 cm
adults are 4.5cm and like a temp range of 24-28c
also known as Albino pristella, Pristella, Pristella tetra and X-ray fish
Yup, if you've got the space for them, they are a very nice little tetra. Easy to keep, easy to feed, non-aggressive, active. Do best in soft acidic water, but that is by no means essential.
hm, those are not the ones i saw. they were labeled x-ray tetras at the lfs, but didn't look like those. they were transparent like the one in the photo, but were slimmer and the transparent was more of a peachy color rather than clear. the eyes were also ringed in black if that makes sense. i'll try to take a photo of one and post to see if anyone knows what they really are.
