Not sure - If it's a species that can be ID'ed by sight, then you might be able to get an ID on it as it grows, but a lot of sponge species can't be ID'ed by sight (a lot of them need to be ID'ed by their spicules and/or DNA).

Anyway, here’s a good Sponge ID resource for anyone who’s interested- as mentioned, though, sometimes DNA is the best indicator for telling sponges apart:
