serpae doings

For now, most of my serpae tetras seem healthy. Only Ziggy is still a little paler and thinner than the others- I think he might be bottom of the heirarchy right now.

Punk still has that white swollen lump on the nose- it's the middle fish in the above picture. Lump is now large enough can see it over the top of profile from the opposite side.

I can't tell if it bothers the fish... who still otherwise is in top shape- untouched fins, good color, spars among the others for top position.

Only this past week have I noticed sometimes Punk hangs back when the other fishes move together through the tank- I wonder if starting to feel unwell.
