Crawfish will eat and quarrel simply over anything.
They are super forceful and regional.
Having said that, on the off chance that you anticipate having other fish in your tank, you need a tank that is sufficiently extensive to hold everybody serenely.
Having a greater tank will diminish the odds that your other fish get eaten by your pet crawfish.
They’ll have more space to swim.
What’s more, your pet crawfish will have his little region all to himself.
Keep in mind however, with crawfish, some other fish in your tank may move toward becoming crawfish nourishment at any given minute.
I generally propose putting forceful fish in the tank and fish that swim close to the best.
Red tail shark, mollies and ax fish can regularly function admirably with pet crawfish.
They have for me in the past in any case.
