I moved my fish along with my two kribs into their new 55 gallon bigger home and all is going well. However I have a question about my two kribs. The substrate in this new tank is playsand, and they have taken to doing some floor-remodeling in "their" cave...I see the male going in the cave for five seconds, then coming out and spitting a mouthful of sand outside the cave, going back in and doing the same thing. Whats up with THAT? He has been busy at it too, their are little valleys inside the cave that are almost bare and little hills outside the cave where he has been building sand piles. Do they like sand? I thought it was a good substrate for them?? What does this behavior indicate? I have some leftover gravel that I can put in the cave area if they would prefer it, I'm just waiting on what you folks think? (c-man, ya out there?? )
Thanks!
Thanks!
