Me too . I want to try daphnia . I think the hardest thing about it is feeding them and finding the sweet spot between too many daphnia and the culture crashing . Like anything else a guy just has to jump in and go for it . No real expense to it so you won’t be out anything other than a little of your time .After I try out grindal worms, I might find a space for a 5 gallon tank to cultivate daphnia. I would really like something insect based that's somewhat consistent. And that I can have year round.
