Some times, after harvesting some small container in a natural pond, with some specimen and samples of soil, alga and plant, it can happen to see in the acquarium occasional and very interesting gueests. In most cases such small critters are not going to breed, sometimes they manage to become permanent guests.
The variety of life forms in natural ponds or vernal pool is so incredibile that each time it is possible to discover new ones. The same pond, in different periods of the year could reserve many surprises.
Isopods are the most diverse in form and the most species-
Like all mites, Water Mites are close relatives of spiders. Like spiders, they have eight legs and soft bodies. They live in marshes, ponds, and lakes. They like shallow, still water with lots of plants.
Water Mite larvae are parasites, and they need a host to live on. Some insects chosen to be hosts include dragonfly naiads, damselfly naiads, fly larvae (including mosquitoes), true bugs, and stone fly nymphs. One insect may carry around up to 20 mite larvae. Water Mite larvae munch on their host while it carries them. When a mite larva has grown enough, its exoskeleton (outer shell) becomes bag-
When the nymph is ready, it leaves the host. The nymph has eight legs and looks a lot more like an adult Water Mite.
Gammarus is an amphipod lt crustacean genus in the family Gammaridae. It contains more than 200 described species, making it one of the most speciose genera of crustaceans. Different species have different optimal conditions, particularly in terms of salinity, and different tolerances; Gammarus pulex, for instance, is a purely freshwater species.
How to raise: I found one after harvesting a pool but it never happened a second time. I have never seen an adult one in the pool too. The small one lasted for around 3 weeks, getting a little bigger then it disappeared. According to on-
The rotifers (Rotifera, commonly called wheel animals) make up a phylum of microscopic and near-
Vorticella is a genus of protozoa, with over 16 known species. They are stalked, inverted bell-
How to rise: I have not yet really understood how to ensure a nice growth of vorticella. They sometimes appear as a white milky stain on the glass of the acquarium and fast develops to cover the whole surface. As fast as they appeared, they disappear. I am trying to understand if the PH or water pollution play a role.
They can be nicely observed with a 60-

Cloeon dipterum is a species of lt mayfly with a Holarctic distribution. It is the most common mayfly in ponds. It has long, hairy tail appendages and can swim well with a wriggling motion.
The soldier flies, are a family of flies. The family contains about 1,500 species in about 400 genera worldwide. Adults are found near larval habitats. Larvae can be found in a diverse array of situations mostly in wetlands and damp places in soil, sod, under bark, and in animal excrement and decaying organic matter.
