Fiddler crab with sorority?

I saw today they are good for algae control. How are they with bettas?

Fiddler crabs need salinity in their water, which will kill a betta in the long term.

5G - 1 betta: orange dalmatian VT male "Ty"
29G - 1 orange fantail goldfish "Goldeen"

Fiddlers require a dry land area and brackish/salt water. They would not be a good match for a sorority. What about orange dwarf crayfishes? They're kind of cool and look like lobsters. Or if your sorority has been set up a while you could do cherry shrimp.

Thai micro crabs would quickly become fish food. If you want algae control go for nerite snails.

Everything happens for a reason, but the reason isn't always good.

Nerite Snails and Amano Shrimp destroy algae like its nothing...fiddler crabs come from the ocean and bettas are freshwater.

10 gallon planted - HMDT male betta, 4 peppered corys, assassin snails, Amano shrimp
10 gallon divided bare bottom - HMPK male, 2 VT males
29 gallon sorority planted [journal] - 6 females, 4 bronze corys, trumpet & nerite snails, 3 Amano shrimp

I saw it on a website but they didn't mention the salinity. Maybe I will try the crayfish. I think some of my girls are too mean for shrimp they are picking on my mystery snail a little bit. Something with hard shell would be good. Algae isn't a problem yet but I like to think ahead.
