Combining a peaceful community

Hi all

Until a few weeks ago I had a 197ltr aquarium with different species however at one point they started to attack eachother and most of them got eaten. These are the species:

Prey - the ones that perished:
guppys, neons, koi swordtails,lemon tetras.

Predators - the ones that survived:
yoyo loach, 2x siamese algae eaters, 2x black tetras, 1 med-sized angelfish, black goldfish


The tank has some Cyrptocorine plants as well. Are there species which I could put with the rest ie: the predators?

Thanks
Ramon

Actually, none of the fish you mentioned are predators.

Did you cycle this tank prior to adding the fish? If so, what are your tank readings for ammonia, nitrite and nitrate?

The goldfish is a cool water species and does not belong in that tank with tropical fish.

Yoyo loaches belong in groups of 3, 5 is even better. Tetras belong in groups of 8. If you do not keep species in their appropriate school sizes, you will definitely experience a change in their typical behavior. What might have been a peaceful species may turn aggressive.
