Ok so now that the amonia problem is under control I have a new set of problems. First we just got through an Ick breakout. Everyone seems to have recovered well. However, shrub the treatment and raising of the temperature, my dalmation molly gave birth to about 11 fry! They are all faring well, plenty of plants and places to find shelter. That's not the problem I don't think, the problem is there's this strange ring of bubbly slime going around the top edge of the aquarium? It seems to have just appeared today. I do have 5 snails, can it be from them, if so why is it only showing up just now and what is it for?
