Who ate my plants?
I just got some new Hydrocotyle Japan that I was really excited about. Luckily I split it between two tanks, because someone in my 40 gallon decimated it within 8 hours, tops. It is completely gone, and this was a really nice sized clump. No one has ever touched the crypts, java ferns, apongeton, pennywort, or anubias in the tank - but I can see how the hydrocotyle might be more appetizing than these with it's light and feathery nature just calling out to be eaten.
Anyway, the suspects are: adult keyhole cichlid, mature cherry barbs, juvenile gold barbs, or juvenile leopard danios. I would never suspect either of my sweet Otos.
I'm leaning towards the gold barbs, but I didn't think they were known for being big plant munchers - any ideas?
