this is my first profiling, so be gentle with me.

Size: 13 inches (more common is 8 inches)
Tank size: 3 foot long minimum, but from my experience I'd say make it wider than a foot if you wish it to be active.
Tank level: bottom and mid level swimmer.
PH: 6-7
Difficulty: 9 out of 10, not for beginners. They need extreem care and water quality, and are not forgiving of mistakes.

It is shy and requires a soft substrate as well as fairly good hiding. Tubes and caves made so that it can turn around are advised, and they are light sensitive, so low lights ot light blocking plants are suggested.

Keep singly or in groups of 5+, because in less than 5+ groups, major aggression will come into play.
They also are not competitive feeders, and should be put in tanks with other slow feeding fish, such as peacock eels and senegals who are slow eaters or need to sniff out their food. They do send out electrical impulses, which don't tend to disturb fish usually, but it's not suggested to have them with other fish like black ghost knife fish who use the same sort. They are VERY sensitive to water quality, so much so that even water companies will use them as a guage of water purity.

Here's mine
This is with a peacock eel. there have not been any troubles between the two.

I find holey rock okay, as he never actually comes down to rest upon it.


my personal exp. shows me that they love heavy foilage more so than slate caves, but I have not been able to try tubing yet.
