Blue Discus ( Symphysodon aequifasciata haraldi 1960 )
The basic background color of the body is brown and sometimes brown to red brown. This fish has longitudinal blue striations that runs from the head to the back of the dorsal fin. The head and cheeks are adorned with blue lines. The color of the eyes vary from yellow-gold to red. The anal fin shows blue lines in between with red and also the dorsal fin. Some blues have the black band around the dorsal and anal fin.

Some blues have the striations running across all the body and these are called "Royal Blue." Some of them have these striations running just 2/3 of the body, close to the anal and dorsal fin and therefore, these are called "Semi-Royal Blue".


Discus (Symphysodon spp.) are a genus of three species of cichlid freshwater fishes native to the Amazon River basin. Discus are popular as aquarium fish and their aquaculture in several countries in Asia is a major industry.

Discus belong to the genus Symphysodon, which currently includes three species: The common discus (Symphysodon aequifasciatus), the Heckel discus (Symphysodon discus), and a new species which has been named Symphysodon tarzoo. However, a further investigation published in August 2007 suggested that the genus held the three species: S. aequifasciatus (the green discus), S. haraldi (the blue/brown/common discus) and S. discus (the Heckel discus). Both studies suggest three species; the only disagreement is in the scientific names for each.

Like cichlids from the genus Pterophyllum, all Symphysodon species have a laterally compressed body shape. In contrast to Pterophyllum, however, extended finnage is absent giving Symphysodon a more rounded shape. It is this body shape from which their common name, "discus", is derived. The sides of the fish are frequently patterned in shades of green, red, brown, and blue. The height and length of the grown fish are both about 20–25 cm (8–10 in).

Another characteristic of Symphysodon species is their care for the larvae. As for most cichlids, brood care is highly developed with both the parents caring for the young. Additionally, adult discus produce a secretion through their skin, which the larvae live off during their first few days. This behaviour has also been observed for Uaru species. However when bred in captivity the larvae will tend to live off their parents secretion for up to 2 weeks.

The neon tetra (Paracheirodon innesi) is a

My 6ft planted aquarium.
It's a 180x60x60cm tank, holding 650 litres(160 gallons), has a co2 injection system and a single eheim filter. 4x35w and 2x80w, t5 daylight bulbs +12w of LED evening light.
Substrate is coarse dark sand over a home brewed soil-vermiculite-sand mix.
Plants fed daily.
Don't ask me for an exact water chemistry as I don't know, the fish and plants say it's acceptable though. Plant growth is strong and the fish have all spawned at one time or another, the tetras and corydoras most succesfully.
Flora: Amazon swords, anubias nana and coffeefolia, java windelov and straight, cryptocoyne, brown and green, cabomba, spiral val, pink stuff I've forgotten the name of and a monstrous crinum natans(?). Theres a couple of red leaved lillies in there too.
Fauna:30ish lemon tetras (I gave up counting after the 25th appeared) 7 coydoras julii, 6 siamese algae eaters, 3 dwarf blue rainbows and 3 angels.
