Crawfish problems

[Native Keeper]

Hello! Recently I tried to move one of my crawfish into a new 29 gallon I set up this month. I had a special log cave just for him. But then, about a week after putting him in, he decided to jump out of the tank. Luckily, I heard the sound and was able to move him back into his old tank, which is a 75 gallon. Does anyone know why he would do this? Someone on Discord told me that they heard that crawfish do it when they have air trapped in their shell.

Most times when fish or invertebrates try to leave a tank it's because of water quality high levels of ammonia nitrites or nitrates

@Colu I don't think that's the case, I have a Longear Sunfish living in the same tank and he's doing fantastic, in fact his colors are currently the best I've ever seen them.

Have you tested your water parameters just in case something off

@HydraSlayer; In the wild, Sunfish will eat crawdads, crawdads know this, it could be that the Sunfish got too close to the crawdad for the crawdads comfort. I've used crawdads for fish bait many times and I have done very well with them.

They just do that sometimes, you need a good lid on it. Mine will climb out on the airlines.

@Gator The Longear was not in the tank when the crawfish was.

 

@Colu you are right, I'll do that tomorrow.
