So after 2 redos I finally had it with Aiptasia and Majanos. Got all new rock, scrubbed the tank with Vinegar. Removed all sand, scrapped the walls, soaked the pumps, soaked the mag-floats. One week later I am happy to report no pest Anemones. Never ever again will I allow even one aiptasia in the tank!!!!!!!!!!!!!!! Now for the issue, my YWG that is over 4 years old and my only other fish an adult Clown reside in the tank. Today I witnessed the Clown swimming around in the tank with Goby by the tail. No sand for the Goby but the Goby seems fine without. Has anyone here kept a BB tank and Gobies? I have a feeling this is the last straw and the female Clown will have to be re-homed as she kills anything and everything introduced to the tank. What you are about to see is what happens when you do not ERADICATE all pest anemones immediately, you end up having to re-do it eventually. No kalk paste, no boiling water, nothing nada worked long term. View at your own risk. Any Goby help would be appreciated.
