Overview

Rio Teles Pires Tetra is offered as a qualified Thayeria sp. trade form, not a confirmed species called Thayeria rio teles spires. Each selected quantity is one unsexed fish in the approximate 2 cm or 2.5 cm grade shown in the selector. The representative image shows a straight dark flank stripe and reddish fins; it does not establish an exact species, collecting locality or the appearance of every dispatched fish.

Keep this social tetra trade form in a proper group, with open swimming space and cover. The existing retailer recommendation is at least six, preferably eight to ten where space permits. Plan a mature, calm community aquarium and observe feeding and social behaviour; care labels are not a guarantee that an unidentified form will suit every beginner setup.

They are not a sensible lone-fish display choice. Allow extra swimming room and assess the settled group rather than assuming a precise adult maximum or lifespan from the trade name.

Origin & Natural Habitat

The Rio Teles Pires wording is a supplier trade label, not a collection certificate. A primary taxonomic description records both T. tapajonica and T. boehlkei in the lower Teles Pires area, with similar straight flank stripes. Neither that place name nor the photograph is enough to assign this stock to one of them.

Plants, driftwood and floating cover are practical aquarium shelter, while open lanes allow group swimming. This layout advice does not claim that the actual stock came from blackwater, a particular forest stream or any named wild population.

Tank Setup & Water Parameters

As a provisional retailer plan, keep this trade form in a well-established aquarium of at least 80 litres, though larger is always better for a proper shoal. A group of 6 or more is recommended, with 8 to 10 being even better if space allows. They are active swimmers and will use the full length of the tank, so a longer aquarium is preferable to a tall one.

Use a soft, fine substrate if you want a natural look, and add driftwood, hardy plants, and floating cover to reduce stress. Open swimming lanes are important, but so is shelter. Gentle filtration is ideal; strong turbulence is unnecessary and may make the fish appear nervous. A mature tank with stable water quality will always produce the best long-term results.

Existing provisional retailer water guidance:

  • Temperature: 23 to 28°C
  • pH: 6.0 to 7.5
  • Water hardness: not independently established for this trade form; check current holding conditions
  • Ammonia and nitrite: 0
  • Nitrate: kept as low as practical through regular maintenance

Regular partial water changes, good filtration and measured feeding remain important. The temperature, pH and 80-litre figures above are existing provisional retailer husbandry guidance, not verified supplier or species biology. Ask about current holding conditions, acclimate gradually and favour stable, suitable water over abrupt manipulation to reach a number. Use the water parameter matcher for planning, not as proof of this stock’s tolerance.

Feeding Guide

Offer appropriately small quality flakes or micro pellets, with measured frozen or live foods such as daphnia, baby brine shrimp, bloodworm and cyclops for variety. Observe actual acceptance and ensure all members of the group feed; the trade identity does not guarantee an immediate response to every food.

Feed little and often, only what the shoal can consume in a couple of minutes. Overfeeding can quickly affect water quality, particularly in smaller aquariums. A varied diet will help support growth, immune health, and strong body condition as these juveniles mature.

Tank Mates / Compatibility

Plan this trade form for a calm community with companions of similar size. Ideal companions include other small South American tetras, rasboras, peaceful dwarf cichlids, Corydoras catfish, Otocinclus, and other non-aggressive bottom dwellers. They also work well in planted community aquariums with livebearers, provided the water parameters suit all inhabitants.

Because they are active and schooling, they should not be housed with large, boisterous, or predatory fish. Fin-nippers may stress them, and very slow or long-finned species may be outcompeted at feeding time. A balanced community with plenty of space and visual cover is the best approach.

When introducing new tank mates, always consider adult size, temperament, and preferred water conditions. Keeping them in a species-appropriate shoal will reduce shyness and encourage natural behaviour.

Ordering and planning

Check the selected approximate size and quantity before ordering. Each quantity is one fish, not a wholesale pack or guaranteed sexed pair. Compare suitable companions in the tetra range by space, temperament and water needs rather than by colour alone.

Read the current delivery and live-arrival terms and prepare a mature filter, cover and suitable small food before dispatch. Eligibility and receipt arrangements follow the published policy; the supplier trade label does not certify stock provenance or gallery authorship.

Observe the group after settling and seek advice if feeding or behaviour changes. The guide is deliberately qualified where exact identity, adult size and lifespan have not been established.
