well i dont really have a question but kinda do so lets get started
i have 2 clowns and a BTA in a 60g tank and well i got the tank from someone who was moving and sold it very cheap so i moved it to my house(nightmare) and he said the do spawn but havent for about a month (my guess is stress from the move, and new settings) well i been noticing one of my corals in that tank has been move and looks like its been rolled over(it has a round bottom) well its only like 4ins away from my BTA so my guess its my clowns clearing the area(its the really on flat area around them), and i also know that clowns do clear a area close to their home when they are about to spawn. so what do we think and the only other fish in the tank is a
Royal gamma and he wont go anywhere near the BTA
Peace OUT
