![]() If I put my hand into the aquarium and rub my fingers together, the friction of my fingers undoubtedly will always bring them both out no matter the time of day to investigate. They have been some of the easiest fish to catch because their curiosity always gets the best of them and will voluntarily hop in my net. They seem un-phased by new environments and seem to always go with the flow. From the start, both of my dolphin have been outgoing. My experience with what I believe to be Lacerda is an interesting one. Their personalities will vary among individuals and even more so among species. BehaviorĪs stated before, these fish are a semi-aggressive species. Dolphins will also accept daphnia and possibly crustaceans such as brine and mysis. To avoid risking disease, getting your worms from a reputable source or cultivating your own is recommended. While live is ideal, you run the risk of spread disease this way. I’ve tried clean earthworms as a treat, and they seemed to enjoy these, as well though may be too large for smaller specimens. Variety is best which should include blackworms, whiteworms, grindleworms, and larvae. While bloodworms are easy and can be used, I would advise against using these as the only source of food. Their diet will likely vary between individuals but I found that it’s vital to have worms as a staple. ![]() If you’re into aquascaping and keeping your plants neat, the dolphin will keep you frustrated as they are the Godzilla’s of the plant world making it a game to destroy your favorite plants. You can add in taller plants, but keep them sparingly or in designated spots because a heavily planted tank, especially with tall plants will make it difficult for the dolphin to swim freely and can also get them tangled up. Delicate plants that the dolphin can tear up or un-root while they forage are also not a good choice. For example, a plant that requires a high light is probably an unwise choice since either the dolphin or the plant’s needs will not be met. Use care when choose live plants to house with the dolphin. They spend most of their day burrowing their faces into the sand looking for worms Speaking of which, because they are fairly blind and rely on their electrical pulse to navigate they can and will bump into objects (especially if you rearrange your decorations) so it is important to choose decorations that do not have any sharp edges. This will allow them to display their natural behavior digging around, as well as allowing them to swim freely without bumping into things constantly. While they like a lot of hiding, it is important to have some areas of open water on the ground. A brightly lit aquarium may make the dolphin shy and hide more. They prefer dimly lit aquariums so a lower light or “spot” lighting is a good choice. When kept warmer, they have seemed to breath heavier and were much more agitated. I have found that they have been happiest between 77F-81F, 81F being the warmest. I have found that the temperature they are kept at isn’t as flexible as other species of fish and notice that their behavior changes greatly if the degrees are off slightly. So while they may not require a high PH like rift cichlids, they seem to do best with a more neutral PH rather than an acidic one. I have kept them in a PH that varies slightly between 6.5-7.2 and have not seen a significant difference, though I will say that in the wild they live in the rivers just outside the rift lakes. ![]() They spend most of their day burrowing their faces deep in the sand searching for worms and tasty food, so putting them on anything besides this can keep this fish from behaving naturally. The first important thing is to keep this fish on a soft sandy substrate with no sharp edges that will injure their nose. Low lighting plants Java Moss, Anubias, Crypts, Java Fern. PVC for extra hiding, floating fake plant, anacharis, and duckweed-type for Chipz the gourami and to diffuse lighting more. Avoid other electrical fishĭolphin’s new set up. DifficultyĪ variety of worms, crustaceans, daphinia, will not take pellet Not much is known about this fish still, but I will share what I have gathered. While some may be more outgoing than others, their care is fairly similar. A few species are Mormyrus Longirosis, Mormyrus Kannume, Mormyrus Lacerda, Mormyrus Rume, and Mormyrus Tapirus. There are a few different species under this common name and their personalities vary slightly. The Freshwater Dolphin Fish is a rare fish in the trade and nearly impossible to properly ID.
