While royal clown loaches are fairly peaceful, they do have large
appetites and are primarily carnivorous. Tankmates that are small
enough to be eaten have a high chance of being swallowed. If you keep
them with larger peaceful tankmates, you should have no problems
with this. They will readily accept live and frozen foods, including
blackworms, bloodworms, earthworms, shrimp, krill, and other meaty
items. Over time, they might also learn to accept pellets. Feeding foods
high in carotenoids will keep their yellow and red colors more vivid.
The eartheaters of the Geophaginae subfamily, while popular in some fishkeeping circles, are largely underrepresented in the hobby. Certain species of the Geophagus, Gymnogeophagus,
and Satanoperca genera are not necessarily rare, but they’re still
uncommon enough that you shouldn’t anticipate them showing
up at your local fish store. The few species that do appear from the
Guianacara genus are even less common. Guianacara owroewefi is not
a fish that you will find a ton of information about, and it is still not
seen very often in the trade. But if you do come across a batch, they
are a great fish to keep.
G. owroewefi comes from rivers in Suriname and French Guiana.
As would be expected from their origins, they tend to like soft,
slightly acidic water with temperatures in the low 80s F (around
27° to 28°C). They do well when given a moderate amount of flow,
but should be just fine with only a good filtration unit. You wouldn’t
need to worry about adding additional powerheads or setting up a
hillstream tank for them.
Like Geophagus species, Guianacara owroewefi will often sift
through sand looking for something to eat. At least part of the
substrate in your tank should be planned around this, with small
grain sand that will permit their sifting habits. Aside from that,
hobbyists have had success with a range of tank decorations and
layouts. Rock, driftwood, and plants can all be used to give them a
naturalistic environment in which they’ll be perfectly content.
G. owroewefi is an excellent option for those who want to keep
a group of cichlids without having to worry about the aggression
or providing a lot space. A small group in a 75-gallon (284-liter)
aquarium is manageable, as the maximum size for individuals is
about 6 inches ( 15 cm). While they may try to opportunistically
snack on very small tankmates, they are peaceful enough that
compatibility with other peaceful fish shouldn’t be an issue. Cory
cats, hatchets, angelfish, and other peaceful Amazonian cichlids
could all be potential tankmates if you’re going for a South American-
themed tank. D
