Ok well my Jardini just busted his jaw overnight it appears that he went to get a minnow and scraped it on the gravel really badly. I put him in the Hospital tank and now he is on Meds. This issue has made me decide to go with sand in the 135 gallon. Anyone have good sources in the NJ/NY area for sand? I don't want to buy it at any LFS because it would be very expensive to fill a 135 with that much sand. I have herd swimming pool sand is really good for FW aquariums? Anyone have experience with this? I Prefer black color if there is such a thing?
