Where can you buy these?

Basic coral husbandry must be 100% mastered first before you move on to keeping azoox corals.
If you cant keep sps well colored then dont try any azoox corals above and beyond suncorals, vendors, balanaphyllia etc (all the easy to keep corals they can be fed pellets or frozen)

i've been keeping sponges for years.my blues have spread all over my tank,my yellow has been stable for 2 years & my purple has been spreading as well.the only problem i have is various orange sponges get eaten by my regal angel.i now have a large branching sponge that the regal is not touching.(also lots of cryptic sponges)

This one is awesome, but it is a photosynthetic sponge and under good light it become dark, almost dark gray/black.

I have it and it just started to produce lots of pipes, very nice!

It can burn though, if you press hard enough on it, it can sting.

I'd suggest learning how to culture your own phytoplankton first and mastering regular coral keeping before moving up to difficult Azooxanthellate species.

However if you'd like to try your hand at keeping a small variation I could send you a handful of this one of these days.

The blue haliclona is photosyntectic and it is very easy to keep. Just stay away from chemiclean for cyano as it can kill sponges.
