greech: Thanks for the reply. I think that the goby was starving himself before the crab got to him, but I'm sure their presence didn't help. My rockwork is large, but isn't that stable. Not sure if I will glue it...My tank is only 20g so I'm sure I won't be doing much rearranging anytime soon...
I just lost the goby today. Found him being eaten by an Emerald when I got home from work. I'm not sure if he died because of starvation or because the crabs kept him from coming out of his holes. This only seemed to intensify once I changed to the Aquaclear 50 filter. Hmm...Not sure what to...
I currently have a cycled 20G with an Aquaclear 50 filter. In my tank I have a Fire Shrimp three Emerald crabs and a twin sport goby. I would like to start adding fish but I'm more interested in invertebrates. I really would like a tuxedo urchin but am worried I don't have enough room. Any...
