Fish that Start with J


Fish that Start with J -

Here we are again with another installment of our fish A-Z, this time with the letter J. There aren’t all that many common fish names starting with J but there are some cool ones which are definitely worth a mention.

Each of our fish that start with J has been listed with their scientific name alongside them in brackets so you can learn even more about each of these awesome fish. Scientific names are all in Latin – these names often don’t begin with the same letter as a fishes common name, but they hint at what kind of characteristics the fish have. For example, linneatus = lined or striped, brevi = short and pulcher = beautiful or pretty.

Our Top 3 Fish Names Beginning with Letter J


Jack Dempsey (Cichlasoma octofasciatum)

Hailing from North and Central America, this variety of cichlid is very aggressive. Always keep them in same species tanks to ensure the best experience for your fish and you. In some cases larger, robust fish such as barbs could be kept alongside Jack Dempseys, but that depends on your fishes temperament.

When paired up with the perfect partner, these cichlids can make very prolific parents, continuing to reproduce quite regularly. Little ditches are dug into the substrate in which the eggs are laid and then this area is defended by both parents until the fry are big enough to be moved on.

Jelly Bean Tetra (Ladigesia roloffi)

When we saw jelly beans were in our fish list, we got a little excited and imagined a whole host of cute little bean-shaped fish swimming around. Sadly, this isn’t the case, but it doesn’t take away the cute-factor of these little shoaling fish. Jelly Bean Tetras are peaceful fish that can be kept in a community tank, but they can be a little fin-biting, so avoid tank mates with long fins.

These dinky fish like a tank with plenty of hiding places, so densely planted tanks are ideal! Despite their smaller size, they do like spacious environments so they can swim around with their 6 (or more) buddies with ease.

Jewel Cichlid (Hemichromis bimaculatus)

The second cichlid in our list is the beautifully colored Jewel Cichlid. This pretty fish has some beautiful markings as well as iridescence similar to that of a rainbow moonstone. These vivid colors actually get brighter during breeding!

These African cichlids are semi-aggressive so aren’t best suited to community tanks, so keeping a single species tank is the ideal setup. They like to hide sometimes, so providing an area of coverage or some cave-like structures will keep the Jewel Cichlid happy.
