they get fairly easier as they get bigger. i had 3 so far. my largest one passed around due to some infection still unknown (had a hole on the side of the dorsal fin).
i've kept them now with so cal water, wc straight from the tap, and only feed it market shrimp. As long as extreme water chemistry fluctuations it should be fine. all mine were raised from little (before strips are shown) to the current one i have now of 14".
they are great fishes and a requirement for any showtanks...
if you have any other questions, feel free to PM me or shot me an email.
