Greenwoodochromis bellcrossi, a monstrous predator!

Post by mshuangchao » Sat Dec 28, 2013 8:02 am

Just a few quick photo snaps I caught of one of my bellcrossi. In it's mouth is a N. multifasciatus, which luckily escaped with just minor injury. To my surprise, Greenwoodochromis bellcrossi seems to be a very active predator, chasing smaller fish that are obviously too big to gulp!

Thanks! I should of used my DSLR, but couldn't react fast enough!
The multi is my girlfriends... but she decided to keep other fish so I put it in my tank for the time being... never would of thought that these guys were such greedy predators!

I find this not consistent to what Thomas Anderson wrote on Cichlid News (April, 2012). He wrote that G. bellcrossi is not likely an active piscivore, but from what I have seen, they are very greedy and aggressive predators. My two pieces are F1 from Germany, around 10cm in length. The first morning upon their arrival, they reacted to the feeding frenzy at feeding time. They did not see flakes or pellets as food items, however, they were aggressively chasing my juvenile C.foai which were a good 3-4cm, way too big to be gulped up. Later that night I found one of them with a multi in it's mouth (photos above). Therefore, I reckon they are active predators.

New finding! Greenwoodochromis bellcrossi is a very likely a paedophage! I have observed them lurking beneath much larger fishes with their eyes fixed on the buccal region, sometimes even attacking it!
No wonder I have had no fry in the past few months!

Such findings are certainly probable, keeping in mind its upturned mouth, a mouth shape seen in some Lake Malawi Haplochromines that are paedophagic.

Yes, and it looks very probable to me! I could observe them swim into attacking position and closely observe the buccal cavity for a while before deciding to charge or not. Since none of my fish were holding at that time, they did not charge most of the time, though there were a few charges at the Haplotaxodon, probably due to their large looking buccal cavity. I am giving away these few Greenwoodochromis to a friend of mine since I'm out of tanks, they are not good tankmates if you want anything to breed!

Your observations, coupled with Thomas Anderson's article on them, shows just how plastic this species' behavior is.

Very true, and it seems that smaller fish (under 7cm) are more likely to have this kind of behaviour, I have not observed this behaviour in my two larger fish (around 12cm). For this species, there could be a different ecological niche for different age groups.

It is also possible that this behavior tends to go away in captivity, much like that seen in Nimbochromis livingstonii, where it tends to not display it's death feigning hunting behavior in captivity when it gets accustomed to being fed everyday by the hobbyist.

I should have thought of this too, thanks for the great input!

Would you say that these fish are more predatory and aggressive as the lepidiolamprologus elongatus? just out of curiosity :D

Greenwoodochromis belcrossi with Benthochromis tricoti in 600liter

Hi

i would like ask, what do you think, this an association could work:
Benthochromis tricoti+Greenwoodochromis belcrossi+cyprichromis microlepitodus+xenotilapia papilio about in 600liter?

I do not want to breed, only well-respected my favorites fishes..

thanks
