I just recently watched a video about scuds and how they are a good live food, but I have also heard that they can be like a plague in the aquarium due to their ability to reproduce uncontrollably and pretty much devour anything green. What are your thoughts on whether they are worth it or not? I would be using them for feeding pea puffers, Figure 8 Puffers, Angelfish, and I plan to expand my breeding into discus, rams, corys, and rainbowfish. Are they nutritious for my fish? Do you think I could do a colony of them in a 2.5g?
