Caught them from the wild, had quite a choice at my stream by my house. Hundreds and hundreds of rocks in the stream, and a different sized crayfish under every other one.
The tank is 10-15 gallons. Set up a cave structure for them with multiple tiers. Also took some grass-like plant that was growing in the water and planted it in the substrate (also from the river lol, clay/gravel/bigger rocks). Mainly for the minnows to hide in if they want. Just set it up so it's pretty cloudy
Also, I have a fish in there that only swims on the bottom, has two dorsal fins, shorter one in front and longer one closer to its tail fin. and some black markings on it, sortof vertical stripes. Any clue what it is?
I'm almost positive its either a johnny darter or banded darter, member of the perch family. Very cool looking
