7 things to know before welcoming a Mokelembembe bichir

1. 1Identify It Carefully

   This species was described in 2006, and some fish imported under the name "retropinnis" are said to have been Mokelembembe bichirs. A dorsal fin set far back on the body is one of its features, but telling it apart still takes care. Before you commit, ask the seller about the scientific name, photos, and the fish's background.

2. 2Intermediate Level

   This species is rated as suitable for intermediate keepers. It suits people who can keep up with basic care such as regular water changes and water quality checks. If you are new to tropical fish, it is safer to get comfortable with equipment and water management first.

3. 3Choose a Wide Tank

   The maximum standard length is 26.7 cm according to FishBase, so tank size directly affects how comfortable the fish is as it grows. Choose a tank with generous length and depth so it can move along the bottom. Hiding spots such as driftwood or pipes can help it settle in.

4. 4Lid and Air Access

   Bichirs are known to gulp air at the surface. Leave an air gap between the water and the lid, but choose a lid that closes securely so the fish cannot slip out through gaps. It also helps to seal the openings around heaters and tubing.

5. 5Careful Tank Mates

   Bichirs tend to be strongly carnivorous, so any fish small enough to fit in the mouth may be eaten. Not much is documented about this species' compatibility, so judge tank mates carefully based on how your fish behaves. Fish of similar size with calm movement are the safer choice.

6. 6Feeding and Water Care

   Feeding response varies between individuals, so ask the seller what the fish is currently eating before you bring it home. Uneaten food can degrade water quality, so start with small portions and adjust as you observe. Make water checks and regular water changes part of your routine.

7. 7Lifespan Is Unclear

   There is little documentation on lifespan, so no clear number of years can be given. Plan your tank and equipment with long-term care in mind. Keeping notes on appetite and condition makes it easier to spot changes early.
