I have 2 pufferfish in my freshwater tank. I keep them fed on shrimp pellets, flake food and small common snails. I think that it is crucial that these fish have snails in their diet. They really love to crunch them up. I raise the snails in a 2 litre container with some lettuce in it. Every time I need a new batch of snails, I dump in some flakes, and almost overnight, There are 20 more baby snails. Always leave a few larger snails in the container to ensure that you dont run out.

I have had two of these puffers and love them! They are the most entertaining fish I have seen yet, and they seem to be quite intelligent at times. My fish has taken to swimming up and down the side of the tank, staring at the side as though he was chasing his reflection. The funny thing is, he has taught two cichlids (who were moved to another tank for breeding) and a Silver Scat the same game. Often you will see the puffer start and the scat soon follow. I have noticed since moving the cichlids they stopped doing it. Contrary to what most info says, my puffer is very passive. My first one was a bit more aggressive, but this one won’t even eat a ghost shrimp. Loves brine and frozen bloodworms. My last one ate snails, but again this one will not. I have never seen him nip at another fish, and have seen him chased around by a cichlid and a Chinese algae eater. It definitely varies from case to case, and this one is by far the least aggressive of the two I have had. The scat seems to be a perfect companion, they both seem to enjoy the brackish water, and love to share a meal at the buffet (all the live plants I put in for them).

I'd like the state that even though these fish are freshwater/brackish fish, I have successfully acclimated one to a saltwater aquarium. He shares the tank with a porcupine puffer and Hawaian blue spotted puffer and they get a long great. There are a lot of different types of marine fish in there also and they also get along great. He does not harm anyone but the food. My puffer is still about 5 cm big and eats 4 pieces of prawn about his size everyday. He is a great addition to have!

I have a 5 cm pufferfish that is currently in a 200 L saltwater tank with a porcupine puffer, domino damsel, yellow tang and picasso triggerfish. I'd like to comment on the fact that these fish can be sucessfully kept in either fresh, brackish or saltwater. Please note that they can't be dumped from a fresh tank to a saltwater one and vice versa. If you have one in fresh water and wish to acclimate it to saltwater, it is advisable to do this slowly, over a period of about a month. The fish's ability to be kept in such different types of water is definitely an advantage because of the possible tankmates that it could have. My experience with these fish is that they are somewhat aggressive to their own species and also figure eight puffers, but are not very aggressive toward other species. There is a lot of information out there stressing how aggressive these fish can be, but it is best not to place them in tanks with overly aggressive fish. They would do well in a tank with large semi-aggressive fish. Some possible tankmates might include colombian sharks, mollies and archerfish for brackish water and possibly triggers, porcupine puffers, tangs, foxfaces, damsels and some types of wrasses for saltwater tanks. These fish are very hardy and will most likely survive less than perfect water conditions, provided that there is at least some salt in the water. These fish greedily take almost any live food. Mine only takes live, frozen and freeze-dried foods like brine shrimp, earthworms, krill and glassworms, but I am sure it is possible to get them to accept prepared foods. I'd like to comment on one more thing about these wonderful fish. These fish tend to grow very slowly. I have had mine for over a year and it has barely grown 2 cm; keep in mind that it's also very fat and I feed it plenty of food. So, if you are thinking of getting this fish for your tank, keep in mind that these fish should not be kept with small or timid fishes, but should also not be kept with large boisterous fishes. Large peaceful fishes seem to make great takmates. Good luck!

I have one green spotted puffer (about 4 cm long) in a 20 L tank. Duchess is the only fish in her tank. There is a rather large snail in with her, but I am planning on taking it out. I understand that Duchess requires a larger tank as she matures, therefore I plan to move her soon. Right now I feed her freeze dried bloodworms, tubifex cubes, tropical flakes, and occasionally earthworms. I plan on adding snails to her diet, however. I think she is very happy in her tank at the moment, and I am sure she will enjoy the larger one. I keep her alone because (as others said before) she is a very aggressive species. I love Duchess!

Bought two of these seemingly cute wee specimens for a community tank. For the first few hours they merrily bobbed about minding their own business, so we left them to it. An hour later I noticed a small chunk out of our red-tailed shark's fin and all our other fish cowering in the corner. These fish are dangerous, particularly because they look so sweet.
