Ah, theadonis pleco ! What captivating fish! As a pet shop floor manager, I'm always amazed by these unique aquatic creatures. Let me tell you about this freshwater giant that is the stuff of dreams for so many passionate aquarists.
Discover the adonis pleco: an Amazonian giant
L'adonis plecoAcanthicus adonis is a tropical catfish native to South America. This aquatic behemoth can reach impressive sizes, ranging from 30 cm to over a metre in length! Just imagine the look on my customers' faces when I tell them about this colossus!
Belonging to the Loricariidae family, this fish has a unique appearance:
- An elongated body, wider at the head
- A blackish colour with small white spots
- Pectoral fins with long spines in males
Juveniles generally have more white spots than adults, giving them a particularly charming appearance. I have to admit that I've fallen in love more than once with these spotted little buggers!
An Amazonian whitewater dweller
The adonis pleco is native to the Amazon basin and the Rio Tocantins in Brazil. In its natural habitat, it prefers clear waters with strong currents and a sandy bottom dotted with rocks and submerged wood. This is where it feels like a fish in water, if you'll pardon the expression!
An exceptionally long-lived fish
Did you know that these magnificent creatures can live between 20 and 30 years? That's almost a companion's life! I remember one customer who had inherited a pleco adonis from his grandfather. The fish was older than he was!
Aquarium maintenance: a major challenge
If you're tempted by the idea of welcoming an adonis pleco into your home, you should be aware that it's no easy task. These fish need very specific living conditions to thrive.
An essential XXL aquarium
Given their imposing size, pleco adonis need a substantial amount of living space. An aquarium of at least 1,000 to 1,500 litres is needed to house a single adult specimen. That's the equivalent of a small swimming pool in your living room! I always advise my customers to think twice before taking the plunge.
Recreating ideal conditions
To make your adonis pleco feel at home, here are the parameters to be respected:
| Parameter | Recommended value |
|---|---|
| Temperature | 24-30°C |
| pH | 6-7.8 |
| Hardness | 1-19 GH |
Don't forget powerful filtration and good oxygenation of the water. These fish love currents, so don't hesitate to install circulation pumps. I've seen pleco adonis literally dancing for joy in a well-arranged aquarium!
A decor adapted to your needs
For the well-being of your adonis pleco, provide :
- Numerous caches (caves, PVC pipes)
- Driftwood for him to nibble on
- Rocks to recreate its natural habitat
These facilities will help it to feel safe and to express its natural behaviours. It's a bit like giving your dog a little corner of the Amazon at home!
Behaviour and diet: the secrets of adonis pleco
Although large, the pleco adonis is a rather peaceful and solitary fish. It tends to be territorial, especially as an adult. Its activity is mainly nocturnal, making it a fascinating sight for night-time aquarists!
A varied diet
The adonis pleco is omnivorous, with a tendency to feed on herbivores and detritivores. In the wild, it feeds mainly on :
- Seaweed
- Plants
- Small invertebrates
In the aquarium, you can offer it blanched vegetables (courgettes, spinach), vegetable pellets, and occasionally bloodworms or prawns. I've always been impressed by the way they 'graze' on algae on the aquarium windows!
Reproduction: a major challenge
Breeding pleco adonis in captivity is a real challenge. These fish are oviparous and lay their eggs on a hidden substrate. The male then takes over paternal care. In the wild, this process is well-oiled, but in the aquarium, it's a different kettle of fish!

An exceptional fish for discerning aquarists
The pleco adonis is without doubt an exceptional fish. Its rarity and high price make it a choice reserved for the most passionate and experienced aquarists. Also known as adonis catfish, spiny pleco, L155 and Polka Dot Lyre Tail Pleco, this aquatic giant never ceases to fascinate.
There are two varieties of adonis pleco: A. adonis, with its characteristic white spots, and A. hystrix, without these distinctive markings. Whatever the variety, these fish require a substantial investment of time, space and money.
As a keen aquarist, I can't help but marvel at these extraordinary creatures. Their presence in a well-appointed aquarium is quite simply majestic. However, I always advise my customers to think carefully before embarking on this adventure. The pleco adonis is not a fish like any other, it's a real long-term commitment!
If you decide to embark on this aquatic adventure, remember that each fish is unique. Observe it, get to know it, and you'll be rewarded with moments of pure aquatic magic. After all, isn't that what our passion is all about?
