Hi guys due to financial difficulties I wasn't able to do my monthly water changes like I should, in fact nothing at all for 13 months now. I thought I was going to loose all my corals and was prepared to start selling them if they started to look sad. But they did not in fact they grew and I now have a pest of pulsating xenias and orange mushrooms. Candy cane also got 3 new heads and pin cushion split into 2. It is only the green star polyps that didn't make it they vanished rather quickly! Is it because I have rather hardy corals or will they start dying in the future?? I dosed nothing only fed my fish for the last 13 months. If things stay this way I am not going to do water changes unless something change.
