It could be a matter of settling in.Is it out swimming or hiding?Is it being bullied or harassed by tankmates?
FEEDING THE BEAST & NUTRITION
Now that you have a bichir what does it eat? In their natural habitat bichirs normally at small fish,various
insect larvae and invertabrates.Bichirs are generaly non agressive ambush predators but also
oppurtunistic scavengers.Objects to big to be consumed whole are often "deathrolled" till
small parts are twisted and ripped off the carcass.
Now then what can we feed them? You actually have several options and They will be listed below.
The idea is to vary the diet and try to keep it balanced with an attempt at total nutrition.
The freezer at your local fish store is a smorgasboard of foods which should include
silversides or lancefish
mysis shrimp
brine shrimp
krill
bloodworms
tubifex worms
squid
beefheart
Simply thaw and feed
Your local market can be a great source of foodscheck the seafood section of the freezer
You can use just about any foods you find there including
mussels
shrimp
most fish filets (avoid salmon i think its to oily)
Available at the butcher counter or they should be able to order it for you
beefheart
and yes chicken gizzards
to prepare the above cut it into strips and remove any fat you can find
fish do not digest mammialian fat well
Live foods include
ghost shrimp
earthworms
tadpoles(see next line)
some species of frogs(some frogs relaese toxin when attacked)
African dwarf frogs are a natural part of the diet in the wild
mealworms feed only the recently shed ones the chiton in the exoskeleton
can be hard to digest and in some can result in intestinal blockages.
There is really no reason to feeders except as the ocassional treat.
Various live fish and fry can be used for foods.Caution here unless you raise them
any commercialy bought feeders usually rosie reds/tuffies (the albino form of fat head minnows),
guppies,bait minnows etc.need to be quarantined before feeding them to your fish for several reasons.
reason 1 They are kept in horrible conditions
reason 2 They are often diseased
reason 3 They often are carriers of parasites
During quarantine dispose of the obviously sick or diseased.The remaining ones feed quality
foods a healthy feeder is of course better for your fish.
Goldfish just generaly are poor feeders and should be avoided. they are oily not very nutritious and
constant feed of them causes faty deposits on the liver leading to premature deaths.They also contain
very high levels of Thiaminase a destroying hormone.While many fish used as feeders contain this
goldfish seem to have an abundance of it.Another issue is a spine at the front of the dorsal fin which can
lead to problems if the goldfish is swollowed the wrong way (tailfirst).Yet another reason not to use
goldfish,goldfish farms utilize copper meds in suspension form to combat diseases in the feeders
associated with overcrowding. These copper meds are retained by the feeders for long periods after they
leave the farms. Most lfs invariably retain all or part of the feeders shipping water when the feeders are
loaded into their bins/tanks. And copper does not dissapate from a closed system.
The key is to balance the diet with a variety of foods listed above not just 1 or 2 items and skipping a meal
once you notice a decline in growth rate is good for fish.The sad truth is we as hobbyists tend to overfeed
our charges
Pellitized foods
Can be found in various diameters and include sinking and floating pellets
shrimp pellets
worm pellets
even pellets for cichlids will work
spirulina sticks
brine shrimp sticks
Algae wafers

NUTRITION FOR CARNIVORES
Below are the agreed upon nutritional requirements for predatory fish
below that is a list of necessary vitamins usually supplied and just for informational
purposes.
PROTEIN:: 45% or more (this would be the ideal)
FAT:: 3% Min. to 6% Max.
FIBER 2% Min. to 4% Max
VITAMINS and what they do
-------------------------------------------------------------

mortality
How much to feed?
Under 7''I let them eat as much as they want several small feedings when young are better then 1 or 2
large feedings.I let juvies eat till theres a slight bulge to there bellies
This really applies to bichirs 7''+ I feed mine twice a day skipping at least one day a week
Approx. 80% of their diet is a quality pellet food the rest frozen with the ocassional live feeders after
quarantine of course.Pellets total 2 pellets per inch of fish eg. a 7'' fish gets 7 pellets in the A.M. and 7 in the
evening feeding is then adjusted up or down so all pellets are consumed.Remember a nice round bichir
is a happy bichir-Anne
. My one is huge now but the other is still pretty small.
