Dude can I pick your brain about something? So I just bought a male dwarf cray and moved him with my female cray to a 5 gal mini pond I made with lot's of caves and hiding spots. I'm planning to breed them and move some of them to a 15 gal when I get a colony started. Question is will they actually find each other to mate? I asked some of the people who I bought crays from and they said to put them in a 2.5 cause they might not find each other if the space is too big. I also put a pregnant koi swordtail in there so it doesn't get mosquitoes. I was told by the guy i bought them from that fish won't eat the baby crays. Also I'm adding a leafy non aquatic plant in there but I'm concerned if the crays will climb up on it and escape?
