Hey everyone, I just set up a 10 gallon tank for a crayfish(its got all the decorations, lava rocks, and plants from my established tank since I emptied it out) and I'm not sure if I should have land for him/her.
Most of the care guide I saw didn't say anything about land being necessary, but one that I just poked through mentioned them needing land if I don't have an airstone so that they can breathe?
Currently it's just a 10 gallon tank with an inch, maybe 2 inches max of a fine playsand, and it has a bunch of fake plants, and chunks of lava rock, as well as a few java ferns, some java moss, and some pvc tubes, all but the sand from an established tank.
Should I only have the tank filled some of the way, and have a rock mountain or something for him to climb out of the water?
Thanks for any help, couldn't really find a set answer on this.
