After reading MizTanks comment about loosing the battle with HA and her Kedds Reds colony, made me wonder, "Are some zoathinds or palythoa morphs more prone or susceptible to algae?"
I've actually had a very similar problem with the same morph over the past 5 months. I purchase a mini colony or frag of about 20 heads. Of which quickly became infested with HA and Byropsis. Weekly it seems I would prune the plug. I began to suspect the plug so I changed it. Also fragged the coral. Still issues. I even thought to change glues. All in all its been fragged probably 3 times, on 4 different plugs with 3 types of glue. Still the zoa's become over ran with algae. To this day I have only 3 polyps left and just got done finger pruning them for about 20 minutes. I've also experienced similar or should I say identical issues with Tubb's Blue morph and Bam Bam's morph.
Few thats my long story, anyone else?!
