How to breed the Green Spotted Pufferfish

To breed the Green Spotted Pufferfish, it is recommended to keep more than five fish in a tank to increase the likelihood of mixed sexes. Once a female is recognized, typically distinguished by her larger size after breeding, the spawning process can be managed. To optimise breeding success, a brackish water environment with plenty of flat rocks or pebbles should be provided to give the fish a surface to lay their eggs upon. After laying, the male takes over to guard and protect the eggs. The eggs will hatch in approximately seven days, and the male will continue to defend the fry, moving them to a pit. Raising the fry can be challenging as they have limited food options at this stage, primarily consuming Cyclops nauplii.

Diet & feeding

Green spotted Pufferfish are notorious for their voracious appetite and will eat almost anything offered to them. However, overfeeding can lead to health problems, so it is crucial to provide them with a balanced diet in appropriate portions. Snails are an essential part of their diet as they help keep their beak-like teeth filed down to a suitable size. It is recommended to feed them snails similar in size to their eyes. Along with snails, crustaceans are a significant part of their diet as they are true carnivores and thrive on meaty foods. As juveniles, their diet consists of plankton, cockles, brine shrimp, worms, and whitebait. As they mature, they will consume a variety of crustaceans such as lobster, crayfish, crab legs, scallops, squid, mussels, and clams. A varied diet is crucial for their optimal health and growth.
