It may not be what I want to hear, but I am definetly listening and accepting it.It appears as if you're ignoring the necessary requirements for this fish because it's not what you wanted to hear?
Growing a BGK out in a 100g would work *temporarily* even though I have a funny feeling you're more interested in the cute factor of these large animals, rather than the long-term success factor.
Anyways, because of their weakly electric organ, it is suggested you provide them with a PVC pipe to hide in, as PVC will help block out electrical currents in the water coming from the heater, etc. They'll spend most of their time in there.
Also, they are extraordinarily sensitive to medications because they lack scales. Be wise with medicating/treating a tank with a BGK in it.
They will eat fish smaller than them and they require very clean, soft and stable water.
They are cute, and I do understand they get large, that is why I asked for information about it. It's not like I bought it because it was "cute" the day I saw it, I wanted to get info and everything else..and I still plan on getting one.
