Always watch for behavioural changes too, just after a moult they like to feast for a while and when coming up to a moult they don't want any food anymore.
Just like adults then lol
I feed mine twice a week,but theres nothing wrong with feeding them as much as theyll take,as long as you make sure they take it,or at least kill it
i like to feed mine up so theyll moult quicker,less annoying and fiddly that way
not sure i agree to be honest, there is thought that overfed spiderlings have trouble moulting due to the size of their abdomens. i lost a T apophysis sling that was rather fat, seemed to have been unable to free itself from the old abdomen. might've saved it if i found it in time, but that's sadly how it goes.
i know that doesn't constitute proof, but i think moderation works pretty well. i understand the impatience of wanting them to grow though!
Blackmelo's feeding regime is similar to mine!
though with some of the younger ones that are a bit timid about food and amy not feed on the feeding day, i may check them later and try again, or if they are looking a bit skinny.
