I'm fairly new to plants in the aquarium, but I really would like to start including them in my tanks. I've done a lot of reading about beginner plants for freshwater tanks, but I'm not sure what to start with in my crab tank:
10gal tank-- about 6 gallons of water, the rest is rocky land for the crabs
mildly brackish (~1.005)
2 red claw crabs (male/female)
pH ~8, water is on the hard side
I know my crabs love eating vegetables, so I stuck a few small amazon swords in there as a test (I know it's not brackish but it was the only healthy looking aquatic plant my petsmart had; once I have a better idea of what I want I'll be ordering online). Sure enough, they lifted the plants out of the gravel, clipped the leaves off, and ate the roots. I tried anchoring the plants with heavier stones, and I just woke up a bunch more floating leaves and missing roots.
Can anyone can recommend a good beginner plant that my snip happy herbivores won't destroy? Or at least probably won't destroy?
