Wow. Mine started much the same way back in March. Perfect tank. Beautiful purple rocks lol. Baby was born in May. Spent a week at the hospital. And bam. Dino's. Did massive water changes and it's worse!!! I've stopped water changes. Run socks. But can't let go of my skimmer. Dino's still there. Tiny tiny bit better. Wired most of my turbo snail population died. Weird eh.
