I was in one of the LFS the other day, saw this and thought it looked cool, but I have no idea what it is.
Could anyone give me a clue?
Sorry for the bad cell phone picture.
I noticed this growing in my tank over the last week. It's been getting larger, but I have no idea what it is. Anyone have a clue?
It hard and about the size of a pencil eraser (closeup)
I was looking at my RODI filter the other day and was wondering if the waste water was clean enough to use for my freshwater tank.
Any thoughts? It has to be cleaner than what comes out of the faucet.
I'm thinking about adding a Geometric Pygmy Hawkfish to my reef tank. Would anyone know if it would be safe with my other fish (Green spot mandarin and Solorensis wrasse)? Also have a cleaner shrimp in there as well as other snails and crabs.
TIA
