I got a mandarin dragonet about 6 weeks ago, and he has really plumped up and seems tohave almost doubled in size over that time. The thing is I have no idea if the pod population in my tank is renewing fast enough to keep him going like this or if he's managed to wipe it out after gorging for the last several weeks. Is this sudden growth after introduction typical or do these guys just generally grow pretty fast if there's enough food running around?
