My bigger clownfish suffered a loss as her friend that she had paired with got eaten by a gorilla crab. My anemone has been continuously moving and it might be because of this. My bigger "assumed female" clownfish has been aggressively attacking my new smaller one and I even saw it lock gills...

[Little bit of info/background]: I had this 16g tank running, empty, for months. It never had lights on, only sunlight, and I thought it was cycled based on the ammonia/nitrate being none or low. A couple weeks ago my poor clown was dying and I tried to save him, so I put him in this tank (the...

Hello everyone, I am in need of some suggestions on how to remove a giant 14”-16” head toadstool that has taken over my tank. It is shading out all of my other corals, and it is time to go so I can move on with my reef in a new direction. It has attached most of its body to the rock work, and I...
