Wood, J. The Cephalopod Page. Aquarium Notes — The Octopus; or, the "devil-fish" of fiction and of fact. London: Chapman and Hall. The marauding rascal had occasionally issued from the water in his tank, and clambered up the rocks, and over the wall into the next one; there he had helped himself to a young lump-fish, and, having devoured it, returned demurely to his own quarters by the same route, with well-filled stomach and contented mind.

Plants are definitely a possibility that I would recommend. I think 3 is a good number to start with.
They are not too aggressive so I think should work.
Good luck! Dwarf crays are a lot of fun to keep. In a 54L your only option would really be the dwarf crayfish of the cambarellus genus, which are equally fun to keep and also much more suitable for combining with fish.
Nice post on inverts, I have been keeping reef tanks for decades but it has been a long time since I have had a freshwater tank. Planning on setting up a 75 gallon planted tank and doing research now on what plants, inverts, and fish to add. Some of the inverts mentioned here like dwarf crayfish and amano shrimp would be a very helpful addition to the cleanup crew. I love crabs, I wish there were a bigger variety of freshwater ones available- surely there must be lots of species around the world.
And I had never heard of dwarf crayfishes before. The more peaceful nature sounds nice. The article is about easy inverts after all, haha! And yes, dwarf crays are ideal if you want all the good parts about crayfish without the bad.
Reply Mari April 1, at pm Hi! Reply Rosie May 24, at pm Hello, I was thinking about setting up a L freshwater aquarium, with a couple of dwarf crayfish. Reply Mari May 30, at pm Hi! Reply Agnes April 26, at am What do I need to turn an aquarium into a paludarium? Reply Mari April 29, at pm A paludarium is basically an aquarium filled only partly with land areas!
Reply Arunim March 30, at am I have just bought a 40 litre tank and I am thinking of keeping a variety of of fw inverts in it. Reply Mari April 3, at am A 40 liter tank is a great choice for inverts. Reply brian December 26, at pm i am getting a 10 gallon tank very soon,and i intend to use it for dwarf orange crayfish. Reply Mari December 27, at pm I think 3 is a good number to start with. Reply brian December 27, at pm i will do that. Reply siwan May 18, at pm hello! Reply Mari May 20, at pm Hi!
Others have bilateral symmetrical bodies, such as some arthropods whereby their bodies are divided into 2 equal parts by a midline. Reproduction in invertebrates differs depending on species. Asexual reproduction having no sex or sexual organs is quite common, however, sexual reproduction is more typical. Hermaphrodites are common in invertebrates, this means that both male and female sexual organs are present in one individual. In single sex species, where only one sexual organ is present, males and females do not have to make contact to reproduce as fertilization can occur externally.
Following reproduction, most invertebrates change shape and appearance by going through a process called metamorphosis whereby adults and young have different lifestyles including how and what they feed upon. Invertebrate senses can range from simple systems to more complex organs. Many invertebrates can sense dissolved or airborne chemicals, changes in pressure, gravity and portions of the electromagnetic spectrum including infrared and ultraviolet radiation. Sponges are the simplest form of living animal. These aquatic invertebrates lack true tissues and organs and live attached to a solid surface such as a rock.
They feed by filtering nutrients from the water using special cells and a system of canals and pores. The soft parts of their body are supported by a skeleton of spicules silvers of carbon carbonate or silica. They provide structural support and deter predators. Large spicules, visible to the naked eye are referred to as megascleres, while smaller, microscopic ones are termed microscleres.
Sponges do not have nervous, digestive or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove waste. Sponges are known for regenerating from fragments that are broken off, although this only works if the fragments include the right types of cells.
A few species reproduce by budding a prominence that develops into a new individual, sometimes permanently attached to the parent and sometimes becoming detached. Flatworms are simple worms that are bilaterally symmetrical in shape. They have distinct heads and a flat, elongated, unsegmented body.
