There's always a lettuce leaf in my scat tank, they definently prefer that to the plants, worth considering if you'd like things to be safe from these little aquatic lawnmowers.
whatever that seagrass is that grows with the mangroves... that could be a brachish plant... id just collect some plants from the mouth of a river next time that you visit florida...
:joke: yea your right, i need to pay attention to those KEEP OFF THE DUNE GRASS signs! ~ im just ignorant... dont collect these plants if they are protected!
