My terarrium has an odd new visitor.


I have no idea what this fungus is, but it grew to a height of 4 inches in about 36 hours. There are about half a dozen smaller versions, mere dots only a couple of millimeters in height. They grew from patches of round, fuzzy spores that came from...I have no idea. They could be borne of the soil, as I don't think any of the plants produce such growths. Or maybe they just came from space.

Best thing I did in the last couple of months was to pack the tank with fast-growing plants. The density and growth of Ludwigia repens and Rotala indica have brought my opportunistic algae problems to a complete halt. Complete.

The bottom photo shows my vigilant Rocket killifish, one of two, who occupies the upper layer of the tank while shrimp, small Rasbora, and another killifish lurk deeper in the tank and foliage.
