Pls indentify

I bought the invert last 2 weeks but now the color turns lighter & lighter. Aparts, can anyone tell me the sponge's species name & how or what to feed it? I fed it twice a week with Phytoplex & Combo Vital alternatively but still the colour getting faded.
:angel:

It would help if we had some more info about your set-up, please edit your signature as requested when asking for help! Thank you.

Neat looking Sponge! I've found most large sponges hard to keep regardless of what is fed to them. Phyto is likely a good thing to feed.

God luck

I think that type is partially photosynthetic. Zooplankton & phytoplankton will also help.

pls recommend any website for the species name and other additional infos.

Hey Max,

Firstly let me say.."Selamat Datang" to AquariumPros (that's Welcome in the Malaysian language) as I see you're from Kuala Lumpur.

Sponges are usually not handled properly when going through the "chain line" from collector through to the customer. Rule of thumb for sponges is that they should never be lifted out of the water and exposed to the air. Once that happens air gets trapped in their bodies and they can not expell it. Therefore, the sponge dies from the inside out. That is why you are seeing it get lighter and lighter, as the dead tissue comes closer to the surface.

Chances are you probably won't be able to save it.

But to try I would do the following:

1) Move the sponge into a higher current area, but don't have a powerhead blasting directly at him.

2) Mr.Wilson is right in suggesting that the sponge you have may be photosynthetic as well, if so then is your lighting sufficient. If the sponge is not partly photosynthetic then dim lighting is a good bet.

3) Some target feeding of phytoplankton. I would choose phyto over zooplankton because of the smaller size of each cell. Sponges generally receive their nourishment through "filtration", they bring water in and remove absorbed nutrients, and expell the water.

4) If white or clear cells begin to surface, this is dead tissue, I'd cut it out or off with a scalpel.

5) If die off continues, I'd experiment and cut the sponge into sections and place in various parts of the tank in a final effort to rejuvenate the remaining living cells.
