I looked closer they are pods lol. Just different than the typical ones I’ve seen. I did order some awhile back from algae barn and it was a mixture of different types I used them in a breeding tank . I added some in my display tank last month and never really seen any in my dt until today so it was a surprise and was being cautious because I just found out my maxima clam was dying it had aniptasia lol deff speller that wrong and its mantel receded a lot so was kind of stressing out and happens a pod explosion at the same time haha what else is new everything usually goes nuts at once in this hobby haha no matter how much you use precautions and due diligence
