weird about the mantids. do you feed them other stuff intentionally? maybe you just have hippy mantids!

The bioballs were placed to create some first bio filtration so that the rock would have an easier time when it first entered. I've actually been removing the bioballs slowly over the past few weeks. As of yesterday, they are all gone.

I do feed the mantis, because it is fun!

Nice to see most if not all of the gorgs are still with us!

Yes, the photosynthetic gorgs are doing great! I'm less positive about the others...

The sponges are part of the TBSaltwater rock shipment. As for sponge care requirements...good questions that I can't find an answer for. One source suggests that they feed on bacteria. I am feeding a huge variety of phyto, zoo, fine particulate food etc...but the survival rate for sponges of this kind is very low.
