Tropical Fish Co Editorial Team — Evidence-led aquarium editorial team
How our guides are prepared
We begin with current taxonomic catalogues, scientific databases, original papers where available, and UK welfare guidance. Species-focused aquarium references can supply practical husbandry conventions, but we label them as such rather than presenting them as laboratory findings.
Every material revision records its sources, media rights, internal-link check, mobile QA and publication proof in the site's editorial-quality registry. We do not invent personal experience, credentials, reviewer names or certainty.
Tropical Fish Co sells some of the animals discussed in these guides. Retail links are clearly separated from the informational answer, and availability can change. If you spot an error, use the correction link on the guide so the claim and its source can be reviewed.
Care guides by Tropical Fish Co Editorial Team

Freshwater Angelfish Care: Pterophyllum scalare
Freshwater angelfish are tall South American cichlids, not small community fish. OATA gives 120 litres as an industry floor for a compatible pair and says the aquarium must be sufficiently tall. We prefer planning around roughly 200 litres, a 100 × 40 cm footprint and about 50 cm height for an adult pair, with more space and an exit plan for a group.

Ember Tetra Care Guide: Hyphessobrycon amandae
Ember tetras are very small Brazilian social fish, with a maximum recorded length of 2.0 cm excluding the tail. Keep them only in a fully cycled, stable aquarium. We recommend a group of at least 10 and about 45 litres with a 45 × 30 cm footprint rather than using a litres-per-fish formula.
