Snail & marimo love
My giant marimo in the background :)
Since the last time I blogged about my aquarium, I've gotten a giant marimo ball and two more Malaysian Trumpet Snails (MTS) from Penang e-aquarium. Also, all my apple snails are now in heaven. So... now my ramshorns and MTS have loads of space for themselves.
My ramshorns exploring their crib
A few days ago, I started to notice that my ramshorms' shells were turning white. I read that this meant they were lacking calcium and that my water was too soft (acidic). To alleviate the problem, I added corals that I had collected from a beach and I'm changing the water twice a week, instead of just once a week.
See the sand underneath the gravel? By day my MTS get to hide out in the sand and the ramshorns can glide over the gravel with no trouble.
I think it's working! I also experimented with sand as substrate, but I quickly discovered that it wasn't a good idea because the sand was too fine and the ramshorns got trapped in it. Now I've put gravel over the sand base and it's working well :)
PS: The guys at Penang e-Aquarium also gave me a small stalk of hydrilla. The snails don't seem to eat the water plant and it seems to be thriving. I'll definitely get more of this easy care aquatic plant :)
