I feed my retic (well, 2 now as of 10:00 am this morning! WOO airmail! ) cali blacks and ghost shirmp, about three times a day for two or three days. She is growing, so I am trying to feed for 3 days on and 1 day off. I also offer chopped wax worms, red wigglers, red worm hybrids, and ghost shrimp, but all to no avail.
