Just received from GulfCoast EcoSystems two
Red Ball Sponge (Psuedaxinella lunaecharta) |
I have never kept photosynthetic sponges. They arrived in excellent looking condition. Within 36 hours, one of the two red balls developed a white powdery line. Prior to lights out, I used a toothbrush to remove white powder, yet it was visible again at first light. Is this a bacteria or a fungus and what outside tank treatment is rcomnded. |
