Nasa snails are pretty strong too! They use their borrowing advantage to go underneath and un-earth stuff that are on the sandbed. Nuisance crabs don't show up much until lights out, so you might wanna do a spot check in the wee hours.
Hoho... learning a trick or two from bro fuel? Always eagle eyeing the rose among the thorns!
I would remove them to create more space for their growth. The protopalythoas might overcrowd them. Just be prepared for sacrifices.
It smells like Dettol. You are biased.
I had a colony of zoas that were not opening up for weeks. Dipped it once in Coral RX and part of it opened up nicely the next day. The rest were probably too far gone to be salvaged, so melted away. The good parts are still doing ok as of today. I would recommend it too.
Your title stated "Europa zoas for bid", but you're selling something that is completely different. If your title says "Europa lookalike zoas for bid", it would have been more forgivable.
Bro, what prompted you to cut the skin polyps? If the pests managed to find a way in, wouldn't it be purged if you just soak the coral in Coral RX solution?
Sounds sadistic, but I actually enjoyed watching these pests die...
