Is taking seaweed such as red algae or green algae ok for an enclosed aquarium?
I have a green mandarin that needs lots of copepods for food and I've only had the tank running for like...4 weeks and I feel like it may not be getting enough food (30 lbs of live rock in a 29 gall tank).
So if I were to go to the beach and take some of the algae back in a big bucket, then put it into my tank, would that be bad? Plus there was some red algae that I saw at the beach that was beautiful, very branchy and floated around and I think it would look great in a tank as well as being a breeding ground for copepods. What do you think?
If not, any ideas on how to get more copepods without making/buying a refugium?
