What is a good food to feed gourami, kuhli loach and cardinal tetras. Something that is nutritional and all of them will like?? I was thinking freeze dried blood worms?? anything better?
Stick with a decent flake or pellet food for a staple diet and give them frozen treats once in a while, say once or twice a week. I prefer frozen foods over freeze dried. Frozen foods won't give them all the nutrients and vitamins they need though. You can give them peas, spinach, courgette etc once in a while too. Just experiment and see what they like. Frozen brine shrimp go down well in my tank.
