New Member! Giant Danio Question

Sounds pretty cool but after hearing what some people would suggest you are not going to know what you want haha. There are so many options. I personally am looking at setting up my 90gallon that I have not been able to for so long because of money issues and I want to switch my Green Terror and Jack Dempsey to it so they can have some room to really move around. But I don't know how much you have looked around you could do stuff like Jacks, Terrors, Sevs I believe not sure. I can't even think of everything so many options explore the site and you will find some amazing looking fish that you will end up wanting to keep.

Giant Danios are neat critters, I've had a few in my life. They can be nippy to other fish I've seen 'em pick tricolor sharks and minnows apart, it can be a balanceing act to keep something small enough to not eat them and big enough to discourage agression. I had 8 in a 75gal with an African Brown Knife and they were fine together but ABKs are hearty fish.

I don't know the answer to your question, but I've wondered the same thing about the different varieties of tiger barbs. Hopefully someone who knows will give some input.

I think it depends on how one grew up. If it was around only of it's kind then it may not accept others but if it grew up in a mixed group, it shouldn't matter...kind of like a baby chick. However since their body shape is the same...they may go by that.

Fish readily hybridize all the time. They are still the same species, so I dont see why they wont still school. Ive seen plenty of schooling fish, that when kept alone simply joined another species group. Ive had neons school with cherry barbs, and serpaes school with buenos aires tetras.

Pretty sure they will all school regardless as previously mentioned. I had my giant danio's school with themselves, with neons/cardinals, with red eye tetra's and with bala's all in the same tank. 3 species I've seen and know of is regular ole giant danio, pearl, and gold.

Be weary though, they are a very fast fish. You basically need to overfeed them to feed your other fish. I had them with my denison's and my danio's would school with them, but when it came to feeding, my god my danio's were fat and my denison's were normal. By no means are denison barbs slow either.

As far as having a main event, have you considered a pair of german blue rams? Pictus would be a great thing in that tank. The only thing I could think of to make it a bit better would be a small shoal of corydora's. Only issue is size because if the cories are too small then the pictus will pick at them, so getting smaller pictus with decent size cories should solve it. Feeding at opposite ends at the same time so that both cories and pictus get well fed. As the pictus's will be like the danio's and be food grubbing.

There are a few different varieties of the Giant Danio. Look up Devario Sp. they all look a like you'd need to have them all side by side to see the differences..
