SAHD help

[shell477]

Have a trio of SAHD and all are quite placid. About four weeks ago, one female (who has been the least placid of the three) suddenly became very skittish and will not be held at all and runs away. Over the last 2-3 weeks she has barely been eating, eating enough to be alright but only just. She refuses to eat crickets most times they are offered, and on the occasions she does eat it is only ever fruit. There has been no changes in habitat or feeding schedules recently, except that we moved from medium sized crickets to large, which the other two are eating fine.

Any suggestions as to what could be going on, and any suggestions to get her to eat more?

They are about 1 year old, two females and one male that we can tell by color and patterning.

Thanks in advance shell
