Some Crayfish Advice

[Shiki]

Hi All,
So I setup a new 20 gallon tank and I want to put crayfish in it and (yes I'm being brave) fish.
I'm looking to do 1 blue cray, one white Specter.
So my questions are:

1. What are the best hides for them? I'm thinking cichlid rocks? What other suggestions?
2. For other tank mates i'm thinking bloodfin tetras and Amano shrimp

Thoughts?

Crayfish are mean. I tried putting shrimp with my 2 and in less than a week they were gone.

I would do some fast fish like danios that they can't catch.

About any rocks or driftwood will do. One of mine hides under the sponge filter lol.

What two do you have and what size tank?
And I have a 15 gal with 2 marbled crays and they like hiding under the moss ball or the green machine lol

It's just 2 wild caught babies in a 2.5g

Try a 1" PVC tube from home depot. A favorite of all of my crays.

Shrimp will be torn apart, fish probably won't stand a chance (unless you do top dwellers)

i had a marbled cray with fedder goldfish for a while (i removed them because i didn't want the Goldies to eat the babies). but i would start with just the cray i have 1 in a 20 gallon and i love him i think the tank is better without fish. i would get the cray and then if that is not enough then you could TRY to add fish. the marbled crays are mainly vegetarian and not as aqressive as all the others, and they have smaller pincers so i would not put feeders in with white cray or any other because they would die.

Since my last involvement with this thread one of mine became an escape artist so now I have one crayfish and a mystery snail. I keep live plants(hornwort, 1 shoot of anarchis, and Java Fern from my planted tank) with with him to soak up nitrates and he does just fine even though he will outgrow the tank one day.

I did have mondo grass and bamboo in there and just moved them to pots today to see how they would fare.


I do top offs almost daily and a cup water change every other day. He's happy I'm happy. Always roaming the tank now since the other one left.

So id be fine putting one crayfish in a 2.5g with some caves and plants and do daily water changes? What kind of filter should I get? A sponge I'm assuming and some air stones?

A sponge will be fine and yes daily water changes. Daily honestly isn't bad at all on a tank this size. I use a syringe to dose my prime for the tank accurately.

Others may disagree but I think a crayfish in a 2.5g is fine. Mine will outgrow the tank but something like a dwarf crayfish probably won't. If you have the option to go larger like a 5g I would. This is just a tank I spruced up because I had it laying around.

I have air stone just as decor and extra aeration. It's not needed really.
