Hi monsterfishkeepers!

I have a big problem. I have a crazy fish mix in my thank that dosn't work. So I need to sell some of them . What kind of my fish would you keep, and why?

My fishes are:
1 Polypterus Ornatipinnis
1 Gar ( I think its a spottet gar, maybe florida)
1 Hepsetus odoe
1 Catfish TSN
1 Tetraodon Palembangensis ( been chewing on the ornates tail )
1 Oxyeleotris marmaratus,marbled goby ( I bought cus I thought it was a wolf fish)

All of them a really hard to find in the Lfs in Norway, so it's not fun to get rid of any of them. Only problem is that I only have a 50 gallon tank. Yup I know it's waaaay to small, but im going to get a bigger one as soon as I can find the room for it (small apartment ) All of the fishes are very young and small.

keep the bichir and the odoe(Tiger pike), both are monsters in their own right but dont need a huge tank to be happy. tsns get waaayyy to big, the fact that the gar might be a florida rules him out, puffers are evil, lastly that goby hits 3 feet, good luck housing it, so ya d keep the moderatly sized ornate and pike both are rad fish (i have had both) and dont get toooo big

Thanks for the advice. I like the bikir, it was my first fish. I'm almost sure im going to get rid of the TSN, puffer , and the Goby. But the gar!, not sure. Had to drive all the way to Sweden to get it. I'm going to post a pic to identify it, but it's very small right now, even to small for my biggest tank.

Anyone else got a opinion??
