Green Spotted Puffer Genus: Tetraodon Species: T. fluviatilis or T. nigroviridis Maximum Size: 7” Aggression: High Temperature: 75-82 F pH: 7.5-8.5, T. fluviatilis prefers slightly higher Hardness: 15-30 dH Brackish Tolerance: 1.005-1.010 juvenile, 1.010-1.025 adult Minimum Tank Size: 30 gallons Feeding: Chopped shellfish, pieces of frozen fish, frozen krill, blackworms, Mysis shrimp, Pond Snails and Ramshorn snails accepted. May accept dry foods but should not be central to diet. Hard foods are best to keep teeth from overgrowing Notes: There are two commonly sold species of fish which are sold as the Green Spotted Puffer (GSP). Identifying based on physical markings is not reliable and requires analysis of DNA to determine which species is being kept. Both kinds are very similar in terms of habitat and personality, so it doesn’t make a lot of difference which is being sold.

The GSP is a very messy fish and requires a tank turnover of at least 6 times tank volume per hour. In very high end brackish or marine conditions, Live Rock and Skimmers can help reduce waste levels. These fish can be unpredictable in terms of tankmates. In large tanks, groups of GSPs may coexist for a time, as well as with large, hardy fish like Scats and Monos. GSPs are very aggressive fish, in addition to being fin nippers, and can easily damage or kill tankmates. Cohabitating with other fish is a gamble and often results in one or more dead or dying fish.

It’s worth noting is that the GSP, as with most puffers, is sensitive to most freshwater medications (especially those including copper). Other medications should be used when attempting to fight illnesses. GSPs are capable of biting their owners as well, and care should be taken any time tank maintenance is being performed.

"There are few fish as endearing as Arothron nigropunctatus (aka dogface pufferfish or blackspotted pufferfish), with its big expressive eyes and pouty little mouth.”

That’s my baby.

Please excuse the flash, and the scuffed eye. The one on the left is my cobalt blue, Sid. The middle fish is my new thunder snakeskin, still to think of a name for him, and then my tiny white butterfly behind him.

How awesome are his markings though?! Can’t wait for him to get biiiiiiiiiiiig!

The sweetest begging puff eyes.

Hyooman I love u FEED NAO. OwO

Probably the best shot I’ve gotten hands down to date.

WOAH WHATS THAT ONE DISCUS STRAIN THAT LOOKS LIKE ITS ON FIRE

TELL ME

IVE NEVER SEEN A DISCUS LIKE THAT

GIVE IT TO ME

Any thoughts on what is happening with this male black ruby barb? He seems to be being chased around by other males and I THINK someone took a bite out of his tail. Or is it fin rot. Can't decide. I have 4 males and 1 female. Should I add more females do you think? In 60gal with perfect water parameters. All other fish look good. Thoughts?

USING LIVING FISH TO STUDY ANCIENT EVOLUTIONARY CHANGES: How plasticity works in evolution race

Ambitious experimental and morphological studies of a modern fish show how developmental flexibility may have helped early ‘fishapods’ to make the transition from finned aquatic animals to tetrapods that walk on land.

The origin of tetrapods from their fish antecedents, approximately 400 million years ago, was coupled with the origin of terrestrial locomotion and the evolution of supporting limbs. Polypterus is a ray-finned fish (actinopterygians) and is pretty similar to elpistostegid fishes, which are stem tetrapods. Polypterus therefore serves as an extant analogue of stem tetrapods, allowing us to examine how developmental plasticity affects the ‘terrestrialization’ of fish. How else would you find out what behavioral and physiological changes might have taken place when fish first made the move from sea to land over 400 million years ago? putting a fish walking on land. To find out exactly what might have happened when aquatic animals first moved to land, Researchers took 111 juvenile Polypterus senegalus a fish species that goes by the common name Senegal bichir, or “dinosaur eel" — and raised them for eight months in a terrestrial environment. This environment consisted of mesh flooring covered in pebbles and just 3 millimeters of water — a precaution that, combined with water misters, prevented the fish from drying out. The researchers also formed a control group using 38 fish growing up in their usual aquatic environment.

Dinosaur eels also have gills, but they breathe at the surface regularly to increase their oxygen supply. They also occasionally use their fins to walk on land. Results raise the possibility that environmentally induced developmental plasticity facilitated the origin of the terrestrial traits that led to tetrapods.
