new bichir tank

[Infblue]

thanks your pictures.
can you tell me what's in the canister?
do u have two filtration-system to process water ?
thanks.

those are filter pads inside the canister. The manufacturer calls it polystrand filter pads. They came with the canister, and I use it to polish the water. The pads are of three different fineness (100 microns at the water inlet, down to 50 microns before the outlet)

it's just one filtration system. There are two overflow drains from the fish tank (from the two back corners), each one drains into one sump tank (the two are connected). The water first goes through prefilter pads (mechanical filtration), and then through the bioballs (biological filtration). I place carbon in the sump tanks when needed. Finally i use two pumps to return the water to the fish tank (left side pump pumps part of the water through the UV; right side pump pumps the water through the canister).

ideally all the water should go through the UV and canister before returning to the fish tank, but I don't have enough space to do that. What I did should still be ok, but not as efficient for sure.

p.s. i also place the heaters inside the sump tanks. A large portion of the sump tanks are used for bioballs (about 1/3 submerged in water, the rest above water)

Nice try of the mirrored one. And, you have a polli as fat as mine.

I understand, thank u for ur help!

i think feed bichirs is like for long, someday,maybe u will re-build a large tank than this. i wish, that tank is very large and you can swim in whith your bichirs.

you're welcome.
but most bichirs don't get too big, so i may not be able to see them in a very large tank

which is your biggest and how long is it? i guess it's p.endi cong..

what are you feed them?

i have a P. endli. congicus and a P. teugelsi that are about the same length, ~21.5" or so. So it's not a monster congicus yet. But the congicus is a lot more massive than the teugelsi, as you know.

the other congicus you asked about (fourth pic in post #14) is my second largest congicus, ~19.5", of course not this big in those old pics

but my longest fish is actually one of my tropical gars, Atractosteus tropicus. This is my favorite gar species, beautiful, and stays at a manageable size. my biggest one is ~23".

i feed them Hikari sinking carnivore pellets, Hikari massivore delite, frozen fish (tilapia, smelt, silversides), frozen shrimps/krills, bloodworm/small earthworm for small bichirs. i want to try loaches, but i can't find them here. I feel that fish grow faster on live food, or freshly dead ones, but we don't have much selection here.

A bichir 21.5" is also large,my p.endi endi has only 19" and growth slowly now. the other endi congi is beautiful too i never seem,stripe on it's body has very singularly i like. a-ha,my p.endi congi has very small only 14",i can't sure,how long it can growth bigger than my big p.endi endi....btw,my tank has small, it's size for 47"*17*23"(H),i think that's importance restrict.

I saw your very large gars,in china, this kind of gars we call it with "ghost-rocket",because it's very crazy and very devour fish. sometimes,it's ate other fish we feed in tank. On the other hand,bichir like a tube, easy to devour by this gars ,so we usually careful & wariness to feed it.I have a little gars, i don't know what kind is it, but the guy usually devour and growth fast too ,that's 15cm/month,below is old picture.

I usually feed them loach they like.i have a queston, how long your bichir food to feed them? i feel, big-fish rather than small-fish to feed them.so,my bichir's food are all big than 4" recently, i think the loach maybe more and more by next feed.

The other question about your filtration:
Do u set two overflow drains near water surface? how can clean bichirs dejecta in bottom tank?is it automatism decompound by biology?

wow, what types of substrate are you using?? i really like the look.
