14 Life in a pond Bitterlings (Rhodeus amarus) (6 – 8 cm/2.4 – 3.2 in.) These cyprinids are difficult to breed as the female requires river mussels or painter’s mussels for laying her eggs. Due to their small size they are especially suitable for small ponds. Sterlets (Acipenser ruthenus) (up to 100 cm/3.3 ft.) Being bottom oriented fish, they mainly spend their days and nights above the bot- tom gravel and dig for worms, snails and crustaceans in the mud. Golden tenches (Tinca tinca) (25 – 30 cm/10 – 12 in.) The calm and easy-to-keep golden tenches are very useful fish. They clean the bottom from uneaten food etc. Aquatic snails are their favorite food. However, they can be observed in the shallow zones only at dusk or when being fed. Gudgeons (Gobio gobio) (up to 20 cm/8 in.) These bottom-orientated shoal fish grow slowly and hardly ev- er reach 20 cm (8 in.) in length. Gudgeons feed on bottom dwelling invertebrates.
