View Full Version : Types of Crabs as Tankmates for Betta?

05-09-2015, 06:25 PM
Hello all,
I recently received a healthy, cobalt blue male betta - which I have since named Neferirkare Kakai (after an Egyptian pharaoh) from a friend who made a misinformed purchase, but I cannot place it in either my shrimp tank nor my 300 L tropical community tank, as the former has numerous berried shrimp and the latter has gouramis - which I soon realized were being attacked by the betta (no harm done that I can see, luckily): Hence, I now am forced to have it in a 6 L fishbowl until I can get a proper tank for it :scry:
In any case, I was wondering if any sort of freshwater crab(s) would be acceptable as tankmates for the betta fish, and if so which ones. If not, I'm wondering what other inverts, if any, would do well with my new betta.
Thanks all! :ssmile:

I have a betta in a 10 gallon tank full of shrimp, he doesn't bother them at all....but all bettas are different

Maybe sounds strange, but recently bettas killed a quite large shrimp Macrobrachium a minute after molting in my friend's tank :sconfused:

Hard to say with crabs, I know fidlers will catch fish if they can. Same with most crayfish/lobsters. There is this that my work


He would have a problem getting a betta because his claws are small.

Thanks for all the advice! I think I'll try a Mexican dwarf crayfish or two eventually, but I think I'll wait a bit to see how my betta is doing for a while first.
