I wouldn't recommend them either in the scenario here, but saying they are "just a color variant" is a bold statement.

I've read it anecdotally, but my personal observations haven't proved it and I've read a lot of things online with varying degrees of fact. I have never kept a regular with an EB so I can't make a direct comparison of two in the same tank. An EB in a tank with "dithers" is just as boisterous as a regular JD IME though. Based on EBs being selectively line bred to the Nth degree, they do tend to be weaker fish in general.

Fair enough. This seems to be a point of debate, but many observe tangible differences with the color variant, whether it be hardiness or timidity. Last I read, the origins of the EBJD were still unclear.

Jetajockey's comment about the EBJD being selectively timid against other JD males is interesting. Does it fare well against other large species that a normal JD would?

You do realize that it comes down to the actual fish itself right?

You can have an EBJD/JD that is meaner than an Oscar, or wimpier than a guppy.

Mine are also about 5 inches long and are very mellow. Mine also used to eat live food but still never touched the giant danios.

So please, don't make a full generalization that they will kill other fish.

Yeah I do know it depends on the fish but in all my experience with JDs have been they are aggressive

Easiest thing to do is trade in your danios and get the EBJD. With trade in the jd may be cheaper or even free. Also if it's a baby you could combine them and move the other fish out once it's a little bigger.

Hmmm, I did not know that. The guy seemed really sure. I can't wait to go.

I didn't even think about trading a fish in. I'l have to ask about that. In about a year or two, I want to get a 125G. So moving some fish around may be an option. I just saw a picture on the threads of an Eletric Blue Ram. Such a beautiful fish.

Yeah, I have pretty much decided not to get one. I need to find another fish that I like. Thinking of an Electric Blue Ram.
