I did glue it down because I thought it was probably a hammer, from that moment forward it seems to be trying to get off of the plug, but it also seems to be growing. Should I try to take a razor blade and get it off the plug? It seems like it is ok so I have just left it alone. Today I looked at it closer and it does appear to have a mouth but it's tiny so honestly I'm not 100% sure. Another thing I haven't mentioned, it stinks, like from day one it has always smelled funky and it still does. I do try to target feed it a little but I can't tell if it is actually eating other than that it puffs up when I feed the tank. I feed reef roids once a week, fresh hatched brine shrimp once to twice a week and I feed my dendro a frozen mix daily.
