no worries,
i got a similar sized sanchezi a month or two ago and he is still shy
for the first week he sat in one spot and only moved for food (ive still never seen him eat- but i havnt really watched i just drop food in and go)
when the light is on he swims a bit but not tons but after the light is off when ever i pass the tank he is in a new place so he seems to be more active in the dark (feels more safe i guess)
