I'm looking at buying a tang .
Either a powder blue or a blue hippo tang .
Are they dirty or is the warning more towards them being aggressive ?
And about the sand sifting goby .
He has cleaned up everything very well ,
Be seams to be able to consume and clean up the sand faster then anything will build .
Any suggestions for feeding him to assure he is getting enough ?
