question about sponges

[jessinator752]

i have an orange tree sponge that is starting to die. the edges are turning brown and slowly disappearing. what do i need to do different? i've had it for about 6-7 weeks and it's done good up until this past week. i have it in a low light area behind some rocks. it was attached to a small rock, but i noticed that it is no longer is attached. i don't want it to die, and i can't seem to find an answer online anywhere. i'm willing to try anything. thank you, jessica
