[marrow]

Marsilea minuta should stay small.( It should not get any higher then the diameter of a dime) I have grown a few varieties of marsilea and my minuta grew the same size in ignored natural tanks as it did in high lght ,co2 ei tanks of course it grew much faster in the high tech tanks. Perhaps you had some other variety and it was stunted. Unfortunately people have adopted the habit of labeling all marsilea as minuta. The vast majority of what I have seen labeled as minuta has been something else. I believe people are acting with the best intentions generally but few actually bother to check a plant key to figure out what they have. This compounds the initial error of course. The other marsilea are very attractive though and they all make an easy low demand foreground
