Today I found out that the two 'cories' I bought from a lfs that where the guy could 'not remember exactly what sort of cories they were' are actually syndontis eupterus. I bought two and they are in a ten gallon with some actual cories, neons, and danios. I have a 55 gallon tank that I will be setting up this summer.
Here are my questions:
-will the two of them be okay in the ten until the 55 is set up in July?
-will they be okay together in the 55, or do they get aggressive with each other as they get older?
-is a 55 even a big enough tank?
-in the 55, will they be okay with a dozen or so peaceful tropical fish? (cories, danios, gouramis, rasboras, that sort of thing? We never really determined what is going in there yet.)
Any other info anyone can offer will be greatly appreciated, seeing as I know very little about them and all the pages I found about them on Google don't give me the kind of info I am seeking.
Thanks so much in advance!

Hi there

Firstly can you please edit your profile so we know where in the world you are! (it's a courtesy requirement of the forums - thanks)

As the fish you bought were clearly not what you thought, or informed by your lfs they should take them back

If you wanted to keep them however, they will be ok for a short time in the smaller tank (presuming if they were mistaken for cory's they are cory sized & not 9" adults!!!). They can be a little territorial as they get older & 2 is not the best choice of numbers but if strategic cover in the form of rocks & bogwood is made available in their long term home you should have few worries.A hidey-hole at each end of the tank will let them have individual territories although in the wild they would obviously have much more space. Although not predatory, some larger synos will (like most large fish) eat what they presume to be food ie tiny tankmates.There will still be plenty of fish to add to their new home to give the tank a bit of movement - a shoal of medium sized barbs, barillius, larger tetras etc which will also act as dither fish

I have a 55-gallon tank that is hexagonal, so rather taller than one would prefer for catfish. However, several years ago I had a large eupterus and a large angelicus, both about 5 inches, in the tank with a few gouramis and larger tetras. No problems. The synodontids learned to feed upside down at the surface as soon as flakes hit the water, but they didn't bother the other fish or each other.

However, I didn't have any corys with them, and I believe that they wouldn't work well with the synos.

I now have these synodontids in a 210-gallon tank, with lots of others, and they are substantially larger, so the smaller tank probably limited their growth.
