Yeah, the slowest of any plant I have kept (mosses, java fern etc grow quite quickly. Lol). They're not limited by carbon levels in the water column though, so can cut through nitrogen faster. I have been pleasantly surprised with how well my 3 have done as red mangroves are said to prefer brackish or marine water.
I'll try to get a nice pic of them.
