Hello! I will soon be trying to create a 7 betta sorority in a 20 gallon tank and I was wondering what else I could put in there with the girls? I've read as much as I could find on sororities but I would be grateful for more opinions on the matter.
Does anyone have a snail recommendation? Ghost shrimp? What about a pair of kuhli loach? Thank you all so much in advance! :) (Now off to take my son to the aquarium. ^_~)
20 gallons and 7 girls leaves you with quite a bit of room.
Kuhli loaches like groups, they burrow in the sand, usually you will see them more if they have a lot of hiding places for them.
Cory catfish are a popular choice on here, there's lot's of different types, and they like groups also. You could easily fit 6-7 of any type with your betta. Just stick to the same species, since they prefer their own kind. Albino, Bronze, and Green Cories are all the same species, so you could get those if you want a variety and mix them. Other common varieties include, panda (the most sensitive, don't recommend), peppered, julii, false julii, adolfo and skunk. It all depends on where you are pretty much.
For shrimp, ghosts are good, as well as cherry and amano shrimp. Shrimp are sensitive little guys, so don't feel bad if you don't have success with them at first. Many betta have been known to snack on them, so ghosts are a better option since they're usually the cheapest variety to have around.
A few nerite snails, or you could get a single apple or mystery snail. Keep in mind your snails will probably produce more poop than your fish, and tend to make a bigger mess than they clean up if that's what you want. Shrimp are much better cleaners.
I have to put my 2 cents in on the corries they are the vutest thing to watch swim around and nibble on food give them places to hide though they are fast and smart enough to swim away but my betta tends to bully them
p.s. My corys love wardleys sinking shrimp pelets... but so does my betta so be sure they get food in a tank with so many mouths
Larger species of cory, such as bronze, *can* work on very smooth, small gravel, but they will still be happier on sand. :)
What is your water chemistry like (pH and hardness)? That will tell us what sort of tankmates you can have. :)
