Hi I recently saw a frog tank online that mixed Dendrobates azureus with Adelphobates galactonotus. They was claiming that they wouldn’t hybridise as they are from a different genus. Is this correct? Thanks

I don't know specifically about frog hybridization details, and there are many, many other reasons not to mix them, but intergeneric hybrids are known from many animal pairings.

Simply being in a different genus doesn't entail that they can't successfully breed, nor necessarily that those offspring will be sterile.

Further, taxonomic revisions sometimes reveal that animals previously considered to be in different genera are in fact not:
