Hey everyone, I have been planning to maybe set up a small tank for a red clawed crab or two. I have a little acrylic 5.5 gallon tank meant for reptiles, but it is leak-free and in good shape. I ran into a little problem though, that tank is my backup for the fifteen gallon and the betta. I found a plastic storage tub by sterilite that is food safe and was wondering it it would be ok to use for a brackish setup. I know plastic is flimsy, but I'm only going to fill it about four or five inches with water so it won't bulge to much. Thanks!
