Actually, I think the goldfish will eat the ghost shrimp once the goldies get big enough. (Which will surely happen. I believe the average length of a well-cared goldfish is six inches.) But I'm certianly not an expert on the subject. Personally, I'm curious if corys and ghost shrimp can dwell together.
P.S. Whoops! I thought you meant goldfish! Now I see you're referring to golden danios. Please forgive my mistake. The heat's gettting to me.im
The platy is risky, the others should be ok with older juveniles and adults. My platys were very curious about the shrimp I put in the tank and nibbled on them. If the shrimp were a bit smaller, I'm sure they would've been eaten.
I have a tonne of neons, mollies, guppies and all their fry in with y cherrys which are about nthe same size and habits as ghosts.
I have not lost any at all, even the smallest newly hatched cherrys are ignored or maybe inspected but left alone by all the fish.
I lost 1 cherry ever when my house mate got a free angel from his sister and threw it in and that was the day after i bought my originall 10 and could only salvage 9 so assume it was eaten.
So as was alreay said, small fish should be ok with them
