Green BTA in trouble

[greg2424]

I have a 55 gallon tank with a green bta, i have had it for a least a year. The last couple months though it has shrunk down from being 5 in round to 1 in. It still eats when i feed it. I have a 260 watt PC. Is there anyone know why it has shrunk down? it doensnt look bad or anything it just became a miniture anemone. It has not gotton back to its original size for 2 months.

Hi! Sometimes they will shrink when resting or rejuvinating themselves-very unpredictable.... very sensitive to changes in parameters:notsure: .
