i have a saltwater tank 36 gallons with live rock and 2 normal clownfish. it’s been running for a while now probably about 3 months or so but i was thinking of adding some saltwater plants. i was thinking of seaweed but i was wondering if i could use fake seaweed, if not then i have no idea where to get real seaweed. pet stores near me don’t sell any so if anyone could tell me links to good websites.
