Help Me Please ...Fish Compatibility
Hello ,
Can someone please give me a long list of fish that can go with mine in a 170 L tank.

I have :
2 orange platys
1 golden gourami
1 leopard ctenopoma ....

(Also could i add a ghost knife fish around the same size ?)
Please answer both of my questions -

:wave:Welcome to Tropical Fish Keeping.

First, what are your water parameters (pH and hardness)? The first key to compatible fish are fish that share reasonably identical water parameters, plus environmental things like plants, rocks, wood, caves, swimming and/or growing space, etc. Then comes the behaviour/temperament of the fish themselves.

You have a 170L/45g tank. The Ctenopoma acutirostre will attain 6-8 inches so it is fine in your aquarium. But although it is somewhat shy as a species, it is nevertheless a predator and will eat anything it can fit in its mouth. So tankmates need to be large enough. Gourami should be fine; Congo tetras are possible, though they are shoaling fish and need to be in a group, say 5 minimum, which would work with just the Leopard Bushfish and a bottom fish or two if small species (some grow to over a foot, not suitable). Or one of the medium-size barb species (also shoaling fish). Or a pair of African Butterfly fish (Pantodon buchholzi) for the surface. All of these fish prefer dim waters, so floating plants would be good.

Knifefish I would not recommend for a 45g. The black ghost knifefish from SA attains 20-24 inches and requires at least a 200g tank--one must recognize the potential and prepare for it if the fish is to be healthy and long-lived. If you had the space, this could be an interesting setup, a group of rather odd fish (Pantodon, Ctenopoma and one knifefish) but this needs a spacious tank. The knifefish is also predatory, and more demanding concerning water conditions (soft, acidic water and very stable to prevent disease).

Nothing to add as Byron has covered it all very nicely but wanted to say, "Welcome to TFK!"

Welcome to TFK!

Do you plan on your your platies being long-term residents of your tank? I asked because your (presumably) juvenile leopard ctenopoma is probably looking at them as hot dogs with fins that he will one day devour with glee. I would keep an eye on the gourami, too, but for a different reason; these two fish are fairly closely related and anabantids are notoriously territorial so I could imagine the gourami deciding he doesn't much like the bush fish. They might get along just fine, though, but it's something to be on the lookout for.

What about some fish for the bottom of the tank? Some type of river synodontis might make a good addition (nothing too big nor too small, though). If the dimensions of your tank will allow it, you could try an African brown knife fish. These grow much smaller than the bigger black ghost knife and would probably get along with the similarly shy, ambush-predator nature of the ctenopoma.
