As a starter my tank is far from perfect, however the other corals in my tank seem to do fairly well ( capanella, lobophyton(?),ricordea, gsp). I have had 2 toadstools in the tanks history (the tank is about 2-3 years old). The first toadstool started well, then slowly (very slowly) shrunk and shrunk ( over the course of months and months, so much so that from day to day you would notice no change). I put that down to poor lighting, and now have a fairly strong led array. My second toadstool, which must be 6 months-a year, looks to be following the same tracks. It never seems to have sustained polyp openings, and its base has dramatically shrunk over time. (looking back at pictures, halved in size). The coral is "host" to a pair of clownfish. I say "host" because it is not big enough for them, and they only really sit around the vacinity of the coral, not on the coral. I'l post picutres up sometime, untill then any suggestions?.... The coral is in no drastic situation, but obviously following how the other coral went, it looks like it will eventually die, and thats not really what i started reef keeping for..

The clownfish could be the problem. Toadstools seem pretty quick to retract so having clowns rubbing on them might stress them out. If the clownfish really aren't touching it while "hosting" then I don't really know... I've had a couple toadstools and found them to be very hardy.

I've changed the position of one of the pumps and it seems to have perked up... my kenya tree was occasionally brushing the toadstool, so i've stopped that now, guess i'l just have ot wait and see

Please send pics. And the usual information. Water parameters...... Could be the lighting, parasites, lack of essential elements, temp. So more information will provide others with clues and probably the answer to help you and your toadstools.
