pratas are easy. almost like brains. choose one with no exposed skeleton, fleshy meat, fully expanded and bright colouration. and dun choose injured and dying specimens obviously. make sure the flesh covers the whole skeleton. price ranges from 6 red notes to 2 and more blue notes. moderate to good lighting, low to medium flow, feed it with meaty food like, once a week or every 2 weeks. advisable to put them on sand so that they do not injure their flesh. however some ppl put them on rock. also can..
i had one prata that i kept in this conditions for quite some time before i sold it off. any more experienced reefers care to correct any of the points i made (if any) thanks.
