why zoos going hairy?

[mark]

Had for about a year, doing good, spreading out, but in the last few week the tentacles have really grown out. Wouldn't by so bad but they're brown and covering the centers, any ideas why? Clowns were hosting but after they stopped is when the grow seemed to have started.

high flow or not enough light.

Also, some are just "hairier" than others. If the clowns were hosting in them, they might've just been more retracted than normal.
