Hello folks,
I will keep you posted - I'm interested in learning more. The photos on the sponge filter are of the largest freshwater blob / sponges. Really nothing new in the tanks. Just my snail breeding tanks, both have shrimp, one with the smaller blob on the silk plants also has mini Cory's who seem to be breeding much to my surprise. If they grow or change I will let you know and if anyone finds out any info on them please pass it along.
I found it funny that the one thing we had about it stated that it's a really clean tank that produces them. Imagine with me what I see everyday - one 40 gallon stocked with half a dozen orange shrimp, 10-12 adult Mystery snails in purple and magenta, a kiss breeder with floating egg clutches and about 60 hatched Mystery snails, 4 adult pygmy corys with 3 noticeable offspring. Now go with me to the morning and sometimes evening feeding where I LOAD them up on an assortment of foods, veggies and some ready made and home made food. - basically overfeeding the snails with the other inhabitants there to help clean up. It's bare bottomed except for a large terra cotta pot - air stone in the bottom and covered with sand, gravel and crushed coral. a few other things in there for hiding and growing plants. It's typically filthy - so the clean comment kinda threw me. The second tank is highly populated with red railer shrimp, Japanese trapdoor, and a few types of rabbit snails - all breeding like crazy with my same typical over feeding. So the whole live , freshwater sponge thing is quite a mystery. Unless something came in on the vegetables. Most recently they are from my sisters garden and she does not use any chemicals.
