Bleeding Heart Tetra (Hyphessobrycon erythrostigma)

You can’t start off a Halloween themed fish list without Bleeding Heart Tetras. This species of fish is a faint pink and/or clear color with a dark pink patch where its heart is.

Ghost Catfish (Kryptopterus bicirrhis)

The Ghost Catfish, commonly knows as the Glass Catfish or Ghost Glass Catfish, is the next species of freshwater fish on our list. This fish species falls into the spooky theme because it is translucent and looks like a skeleton. If you look closely you can see through the Ghost Catfish. You can also see its vertebrae, just like you would on an actual skeleton! This skeleton fish can live up to 8 years under ideal fish tank conditions. Also, a full grown glass catfish will be about 4 inches long. It will require an aquarium that is 30 gallons or larger. You can find Glass Catfish for sale commonly online but a little more sparsely at fish stores.

Albino Cory Catfish (Corydoras aeneus)

Next, we have the Albino Corydoras Catfish. This bottom dwelling fish looks eerie with its very white/tan body and red eyes. It fits the spooky theme for a fish tank because it looks so creepy. Overall, they are incredibly peaceful fish and great additions to fish tanks larger than 30 gallons. It normally like to shoal (school) so having a small army of fish from the undead is ideal. Albino Cory size will reach about 2.5 inches when fully grown. You can easily feed Albino Cory Catfish bottom feeder tablets but they will also feed on any food that falls to the bottom of the fish tank.

Painted Platy (Xiphophorus maculatus)

The common colors for Halloween are orange and black. That is the main reason the Painted Platy falls onto this list. This species of freshwater fish is a beautiful orange and black color that will pop in any spooky themed fish tank. The Painted Platy fish will grow to be 2 inches in length so it is perfect for 10 gallon fish tanks or larger. They are generally peaceful fish and should be kept with other community fish.
