Carp (Cyprinus carpio) are large long-living fish with big barbels on their thick-lipped mouths. They thrive in weedy, slow-moving, warm water and bottom-feed for algae, worms, and insects. They use their whisker-like barbels to find food such as Caddis Fly larvae. They are a very popular for recreational fishing and have recently been stocked here for your enjoyment. It is possible to spot Carp from time to time, as they come to the surface to bask in the sun.

Three-spined Sticklebacks (Gasterosteus aculeatus) are the smallest of the freshwater fish in Ireland. They are also the most widespread of all European fish. They are less than 10cm long with three heavy spines spaced along the back. In late Spring, the male develops a distinctive scarlet coat. With great industry, he builds a tunnel nest of weeds, which he defends aggressively against anything red. By performing a zigzag courtship dance, the male Stickleback entices a female to lay her eggs in his nest. When he has fertilised the eggs, he then chases the female away. He continues to guard the nest and eggs with a jealous ferocity. When the eggs hatch, (after about 10 days), he defends the young until they eventually disperse. It is during the males' colourful courtship display, that the Sticklebacks are most conspicuous.

Perch (Perca fluviatilis) eat fry, insects, nymphs, and small fish such as Sticklebacks. They are predatory fish, lying in wait for their prey under overhanging branches and fallen tree trunks, and among water plants. They are olive coloured with black vertical stripes and conspicuous red fins.

The other fish resident in the pond are Rudd (Scardinius erythrophthalmus). They are a copper and green coloured fish with reddish or orange fins, a bright golden eye, and a distinctly upwardly pointed mouth. They like weedy water and feed on insects, crustaceans, and plant material.
