my first post! hi! .... ya, so on to bichirs. i have 2 senegals (dinasour eels) and have pretty much researched the hell out of how to responsibly keep them. ill be glad to help you out

and ill highlight important points for ya as im sure this will be a good yet long read.
Eating: a diet of something like
hikari sinking carnivore pellets or massivore pellets will be a nice staple diet. you can supplement every few weeks with some fresh diced fish fillets from your grocers freezer if you like. just dont get salmon, its too oily. whiting and cod are good. they are "opportunistic predators" so they wolnt deliberately be mean and try to eat tank mates, it just sort of happens. they have bad eye sight and hunt by smell, so if they get a scent they will take a "test bite" to see if it might be food, whether the other fish is actually too big to eat or not. its not uncommon to find a cory cat or something with a missing tail fin due to being kept with a senegal bichir. ~ and i dont suggest keeping them with cichlids since i have heard of cichlids relentlessly tearing at the bichir's tail, its so big and feathery they cant resist. then again i have heard of bichirs being mean to cichlids.
feeding regimen: they may be fed as little as every other day or up to 3 times a day depending on how fast you want it to grow. power feeding (3 times a day) combined with 50% water changes on a weekly or bi-weekly basis will encourage massive amounts of growth very quickly.
Tank conditions: tank size for one senegal by itself should be at a bare minimum (and still be responsible) 36" long and 12" wide (senegals do not actually get 12" long, 10" a safe bet in the home aquarium. remember those max growth lengths are from the largest ones ever caught in the wild, fish dont get that big in captivity). a 55 gallon or 40 breeder can hold 2, maybe even 3. they are messy eaters and poopers so a good filter, or two, is needed. *****
must have a sand or dirt bottom ***** senegals do not always bite what they intend to bite. i have heard of even 7" senegals dieing because they accidentally swallowed a peice of gravel and it couldnt pass through their system. its a horrible feeling to have a fish and grow it up to that size only to lose it to something and simple as a single piece of gravel. sand is a good way to go.
yes i realize im writing a book here
they dont like bright lights so make sure there is low lighting in the tank. leave the
water level a couple of inches short of the top of the tank so they hae room to breath... they will occasionally go to the surface and take a breath. they have special lungs that allow for use of gills like a regular fish and temporary surface breathing. for this reason they can withstand water conditions that are less than perfect making them harder to kill by accident than normal fish. though i do not recommend letting the water become dirty.
water flow- make sure the tank is relatively calm. this will aid in them finding their food since they hunt by smell.
tank mates: dont not keep with: plecos, sorry, i know you have one but they are commonly known amongst bichir owners that plecos will suck on the senegals scale and cause open wounds. other bad tank mates include but are not limited to: any fish small enough to fit into its mouth, cichlids ( i have seen a picture of a senegal with half of a cichlid hanging out of its mouth, the cichlid lived cause it was to big to swallow but the senegal tryd anyway), any thing that has a mouth big enough for a senegal to fit into and has a predatory nature.
good tank mates: other senegals and a few other bichirs including the delhezi. there is a long list of "good tank mates" but it is all in theory. they may work out, they may not.
water conditions: no specific pH is needed. they adapt. just cycle your tank and keep nitrate levels low and you'll be fine. so long as the ph doesnt swing outside the range of 6 - 8.
thats about all the really important things i can think of right now. if you have any more questions right now just ask. oh, and one last thing.
THE END
lol good novel huh?
