i got questions about these fish...are they brackish??? i read some information about they are brackish and they are freshwater. But which do they live best on? :confused:

ropefish and birchir are not brackish.
I have both and are in freshwater doing fine :-D

i see, will both of them be a fine tank mate with ea other???

How big is this tank..... birchir alone get pretty big, most people can not have a tank large enough to house them.

I am about to try the same thing. I have a 125 gallon tank. Bichir get very big, but ropefish get even larger. They are very similar fish, both will eat anything they can fit in their mouths, but neither are extremely aggressive, and should be fine with each other. As for the brackish question, it is a no for sure. I converted a fresh tank, housing a bichir, into brackish water very slowly, but even so, it stopped eating, became very lathargic, and died shortly after.

my tank is small around 20...saving up for 150...

Than you should wait until you have a tank that can house the first properly.......IMO

Hello Again :D

Size of birchirs depends on species.
Some stay small some grow big and some turn into monsters. LOL
Most you see in pet stores are the small species.

I had to go to a local importer to get a Ornate birchir.($40 for 4" :eek

Ropefish get long not big...LOL
They also grow slow IMO.
I have had 2 and they live in peacefully together.
They will fight over food like worms,great fun to watch.;)

I am sure you can keep one or even two ropefish.
This would limit the amount of fish you could put in that tank.
Only a couple or 3 fish at most.

I keep 2 adult fish per 20 gal in my fishroom unless it is small fry.
(depend on the species of fish in the end,some stay solo :rolleyes


You could research while you save money for a bigger aquarium.

This is a fantastic family of fish.

Good Luck:cool:

You said ropefish grow slowly. What is an approximate estimation in inches a month? Plenty of food in a 125, starting at about 8"? And same question for a 3" senegal bichir? Any experience mixing those two with a clown knife? I plan to get one soon, and just want to make sure the bichir gets big enough to have a fighting chance and to not appear as easy food before I get the clown.
