This loosely allied grouping contains some of the oddest aquarium specimens. They are able to command a good deal of interest when they are on display. Most species need to be given some consideration before going ahead with making an acquisition. Their aquarium companions must to be compatible to avoid disappointments.
Porcupine Puffers (diodon antennatus) are able to take in water like this in order to make themselves too bulky and too spiky for a predator to make an easy meal of them. They may blow up without apparent cause sometimes, but are more usually relaxed with the spines laid flat to the body.
The Long Horned Cowfish (lactoria cornuta) is another of nature’s attractive “freaks”. Although this genus does have the ability to release a powerful toxin into the aquarium water, with disastrous results, it rarely does, and frequently become very tame and knowing of their keeper.
