Neon blue Goby 4-5CM

Neon blue Goby 4-5CM The Cobalt Blue Goby is known from clear, shallow, tropical streams, often in the rapids section preceding waterfalls. Here the water is saturated with oxygen and the substrate consists largely of bedrock with scattered cobbles/boulders. These rocks are covered with a luxuriant, nutritious biofilm (known as aufwuchs) which forms under the favourable shallow, sunny conditions. Riparian vegetation lines the banks of these streams, which over time deposit leaf litter into the water. True aquatic plants are generally not present and few other fish inhabit these specialised environments, with the exception of one or two other species of goby and loach; however, several shrimps and snails are often found living sympatrically. It is important that an aquarium for these fish is planned out in advance so that all their requirements are fully met.
