No to the corys and not sure on the shrimp, but generally speaking they need to be in a species only tank, as they tend to kill or maime other inhabitants.
In a 60L, I would think 3-4 tops, heavily planted.
other than puffers, what other types of fish that are really cool and interesting could i have in a 60L?? i did want a female gbr with corys, cardinals and shrimp and i havent given up on the idea, just wanted to know some cool fish that i could have.
You MAY get away with one single ram, however, I personally would prefer a larger space for them, particularly with cories, as it could cause territorial probs for the ram. I would be wary of shrimps with rams also, they could see them as a tasty snack.
Hi definitely no to the shrimps and any other fish with a dwarf puffer these are the most aggressive of the puffers. Some of the others are okay but 60l is a bit on the small side.
HI ive just had a read up on these and the bare minimum is 3 gallon of water per dwarfe puffer but 5 gallon would be better and loads of tall plants for them to hide. there natural habitat is in and around plants and wood in south american rivers. from what ive read they are not too bad with other fish aslong as they are in a large aquarium but still a very aggressive species. I like these and thinking of getting 1 or 2.
hope that helps and correct lol
