Freshwater Fish
Buenos Aires Tetra.
A big, hardy, silver tetra with red fins and a tireless appetite for swimming. Beginner-tough and great for a lively group, but it can nip fins and nibble soft plants — keep it in a school with sturdy tankmates in a 20-gallon-plus tank.
Live fish are priced per supplier batch — prices may vary. Call to confirm current pricing.

Good tank mates
Semi-aggressive and a fin-nipper that also nibbles soft plants, so it needs similarly-sized, not-timid tankmates and isn't for a peaceful nano community. Keep it in a school of six or more (a bigger group spreads out the nipping) alongside sturdy fish such as larger barbs, bigger danios, or sturdy rainbowfish. Avoid long-finned or slow fish like bettas, angelfish, and fancy guppies, plus anything small enough to bully. Not sure about a specific mix? Call us and we'll help.
Good to know
The Buenos Aires tetra comes from the cooler waters of the Rio de la Plata basin in South America and tolerates lower temperatures than most tropical tetras.
