hi, ive got a male and female occelaris clownfish pair. lately, they have been digging a hole in the sandbed and i was wondering if they were getting ready to lay eggs and if this is where they were going to be. if they are going to lay eggs, i have a pistol shirmp, 2 firefish, and 1 wheelers watchman goby and i dont know if they will eat the eggs. am i right in guessing that they are getting ready to breed?
