The Bush Fish does have a cool mouth/eating method. It was one of the things that I liked about it. However they have a full grown one at my Big Al's and there is no way he could eat a full size Congo.
This is from the onsite profile:
"this is a predatory species and it can swallow fish up to 1/3 of its own size". The Congos are more like 2/3 when they are full grown.
This is from another profile from a site I trust, they actually mention Congos as suitable tankmates:
"Itís quite slow growing though, and it can take several years to reach anything like this size. 6″ (15cm) is considered a good size for captive fish.
Not particularly aggressive but is predatory
and will eat small fish. Ideal tankmates include other species
from the same region. Shoals of congo tetras, Phenacogrammus interruptus
, yellowtail congo tetras Alestopetersius caudalis
and Barbus species
, along with catfish such as Synodontis flavitaeniatus
make good tankmates. You could also try it with other oddballs, such as the smaller species
or the African butterfly fish, Pantodon buchholzi
. Donít keep it with anything too large or aggressive as it has a rather shy, retiring character
Congos are typically 3.5" I think one of mine might be slightly larger than that already. Of course, it's not in a tank with Congos, and if it was in that tank, the Black Skirts would be in trouble long before the Congos.
However the Serpae Tetras are with him, and will have to be moved if they are still in that tank in a couple of years when the leopard fish has grown. They'll be food for sure once he's big enough. The bleeding hearts, if they grow faster than the bush fish, might be ok. If not they'll have to be moved too.
Right now the leopard bush is so small his mouth doesn't open enough to eat a neon. More like a blood worm.
Still no dead fish today, no additional spots and none of the fish seemed distressed.
