I have pet crabs. It’s a really cool hobby and maybe weird to some, but it’s definitely fun. You can see your little critters carrying rocks. Jump off the decorations in the tank, chase the fish, and sometimes get lazy and burrow into their hiding places. – And with two crayfish you can sometimes see them fight.
As for the fight, sometimes it can become dangerous. I had to learn this the hard way with my first crayfish. It was an electric blue crayfish.
Shortly after getting my first blue crayfish, I decided it was time for a second, so I bought a white critter.
At first everything was fine. However, there was a problem. She only had one hiding place in a ten gallon fish tank. The problem of having two crayfish and a hiding place is quite easy to solve.
Over time, my crabs started to fight a bit, but they didn’t hurt each other. Then one day they were going crazy all over the tank and just taking breaks to hide for a few minutes. That’s when I decided to get another hiding place so that each crab could have its own home.
I immediately went to the pet store and bought a second hideout. I thought this would be a great way to cut down on crab fighting.
When I returned home after getting a second stash, I was in for a surprise. Actually, it was more like a blue crime scene. Unfortunately, my white crayfish, which is mostly clean, had ripped apart my electric blue crayfish and was eating it. This was a bit annoying as you could see the blue insides of my white crayfish.
Regardless, to keep your crayfish safe, here are some important tips on crayfish care when you have two or more of the bugs..
keeping them fed
Crayfish often become aggressive when they are hungry. – Kind of like what people do when we’re hungry. The only difference is that we won’t, or shouldn’t, eat one of our own. Crayfish, on the other hand, seem to have no problem eating each other. So be sure to keep your crayfish fed. Hungry crayfish can equate to dead and missing fish and/or other crayfish.
separate hiding places
I’ve already talked a bit about this. Separate hiding places are very important if you have multiple crayfish. Crayfish are very territorial creatures and if you only have one hiding spot in your tank this can lead to crayfish violence. So invest in a second stash.
same species
Lastly, never mix different species of crayfish.
