Question 1

How many blue acara should be kept together?

Accepted Answer

Start with a group of 5-6 juveniles to let a natural pair form, then rehome or separate extras once pairing occurs. Keeping just two unbonded adults together often causes fighting rather than pairing.

Question 2

How big will a blue acara get?

Accepted Answer

Most blue acara reach **6-8 inches** as adults, with males typically larger than females. Growth slows significantly after 12-18 months but continues gradually for a few years.

Question 3

Can blue acara live in a community tank?

Accepted Answer

Yes, in a tank of **55+ gallons** with robust, similarly sized tank mates like larger tetras, corydoras, and plecos. Avoid tiny or long-finned fish, since a territorial acara may chase or nip them.

Question 4

What fish can live with blue acara?

Accepted Answer

Good tank mates include congo tetras, giant danios, corydoras catfish, and other calm, medium-to-large South American cichlids. Avoid small livebearers and slow, delicate species that can't escape territorial chases.

Question 5

What's the difference between blue acara and electric blue acara?

Accepted Answer

Blue acara show speckled blue-green coloring over a tan base, while electric blue acara display a solid, saturated neon-blue body from selective breeding. Electric blue acara run slightly smaller and cost more, typically **$15-$35** versus **$8-$20**.

Question 6

Do blue acara need a heater?

Accepted Answer

Yes, blue acara need stable water between **72-80°F**, which most homes can't maintain without a heater. Temperature swings below this range slow metabolism and weaken immune response.

Question 7

How long do blue acara live?

Accepted Answer

With stable water and a varied diet, blue acara typically live **10-15 years** in home aquariums. This is notably longer than many beginner community fish like tetras or livebearers.
