I wish I could help. I just failed with a baby. Mine had no hardness whatsover and was a gelatinous mass. So I couldn’t glue it.
So I tried rubber banding it to a frag tile but it wouldn’t stay. Then tried giving it a home within a Tupperware container in the tank. I couldn’t get it to settle anywhere and it kept tumbling (my tank has lots of flow) and finally vanished.
I told myself I would make him his own quarantine tank next time with very low flow so he could settle.
Good luck and report back.
