Rob... dont risk it dieing by full on starving...
Its small size still.
You have all the time in the world to convert it... so if I was you.. just add.some chopped earth worms.for one feed
..
Then back to starving... for week or so...
Keep alternating this.... but remember to just do a top up feed ONCE.. not for 2 or 3 days...
I find this triggers the feeding actions of the fish.
And also it will get pissed off with being hungry again... once its had this top up feed...
I do this method instead of eat ot die method.. works all the time... and I have piece of mind it wont starve to death...
May take longer to convert... but as I said... you have lots of time to convert. No big rush... whwn you consider how long these fish live
