Hi @papa-pepper,
I used minnows to feed my jaguar cichlid it was the only fish I could breed that he would eat at the time.
I used a clear plastic bottle cut the top off and turned it around on it's self, glued it back on to make a one way system and I caught loads.
I like your idea of using mesh, I would have tried to use a netting type of material that might not be as big for the minnows not to get out.
Nothing like a nice hot day to go fishing
Steem on brother :D
Oh yeah! I've used three liter plastic bottles before here, and they worked great!
I found the 2 liter ones were good for catching small catfish and the 3 liter ones were cool for the minnows, I wounder if there is away to convert a large food container into something like that, you might catch something bigger :D
