How to feed the Redtail butterflyfish?
The Chaetodon collare is an omnivorous fish with a carnivorous tendency. It is not difficult and consumes almost everything that passes in front of its nose!
For its meals, distribute krill, artemia, mysis, daphnia, mussels, tubifex, fish flesh, Chironomides larvae and even nereis!
It will naturally find the plant part in the aquarium because it consumes the algae that form on the rocks.
What kind of behavior does the Redtail butterflyfish have?
Pacific and sociable, this does not prevent him from being quite active. As a result, he is not aggressive but he is not peaceful either.
It needs enough space to swim freely, while providing retreats and hiding places, which is why a large aquarium is necessary to have even one individual of this species.
It often grazes on the algae it finds on the set.
When it arrives, it may seem a little shy, which is normal. Once well acclimatized, it will not be at all!
Who can live with the Redtail butterflyfish?
In most aquariums, it is preferable to live alone. It is only from a volume of 1,000 liters/ 220 Imp Gal / 265 US Gal that cohabitation with congeners is conceivable. They will then live in groups (in the wild, these fish evolve in schools of about twenty specimens) which will allow to spread possible attacks of an aggressive specimen on several individuals.
For the other species, no particular problem to report except for the very shy species that the agitated side of the Chaetodon can disturb. Attention also with the other species of Chaetodon with which there can be territorial competition.
Maintenance in reef aquariums is not possible. Indeed, the Chaetodon is a natural predator of corals. Thus, it will attack anemones as well as corals, through tube worms.
How to breed the Redtail butterflyfish?
No captive breeding protocol known to date.
Which aquarium for the Redtail butterflyfish?
A rocky environment will be ideal for this species, while leaving enough room on the periphery for this active swimmer. Form holes and hiding places with your stones to make it as safe as possible.
In addition, algae are welcome because they will be part of its diet: you will see it grazing regularly on the scenery.

It is also solid, presenting only few diseases and tolerating copper-based treatments quite well. In short, it is the species of Chaetodon that adapts most easily to captivity.
