Big Feedings Causing Aggression?

[DiscusKeeper403]

Well my angel is being alittle agressive towards my other angel for the first time i've seen. I'm not sure but I think it marked it's territory behind a peice of wood with and a plant I just moved beside it. Is this agression caused from me giving them alittle extra food today for the moving I did? The angel is okay with the other one and won't attack it unless it goes around the wood. The other times there swimming around elsewhere like the pals I usually see them as.

P.S. This really should've gone in the NW Cichlids thread, sorry guys wasn't thinking!

In my opinion, more food should mean less agressiveness within the tank unless it's raising amonia/nitrate levels.

I'm suposing he just really likes his spot, or it's breeding habbits or something. Angel's are quite well known for agressive breeding habbits, and you may have set up a situation that has him or her thinking "I wanna breed"

ouh! That would be so cool if they spawned! Although wouldn't it be alittle lucky if those two I picked out spawned, I mean don't you have to put like 5 in a 20g and wait for them to pair up? Actually with my Blue Acara I had it would attack the fish and kill them when I fed lots. But when I didn't it was fine

I have marine Triggerfish (which are somewhat similiar in habits, but are so distantly related that they are in a different order; Triggers being Tetraodontiformes and Cichlids being Perciformes; but oh well ) that get more aggressive during feeding time. But it depends on the food - a desirable item like a live cricket is much more likely to start a fight than something boring such as a piece of shrimp.

However, Triggers are heavily armoured and otherwise well-endowed - especially in dentition... - mine do scrap but do not do any damage to eachother. However an Angel's dentition outmaches it's armour. You should watch the tank to make sure that a minor scuffle does not turn into a major war, with the fish being injured along the way.

Yeah I'm watching, I don't think it was anything too seriouse. This one that pecked him is the dominte (sp) one of them and there fine right know crusing around the tank with eachother. I think it was more to say "backoff!"

If anything angels showing aggression will call a sort of truce when fed. If there is a little scuffling, then they seem to get along, swimming together or near each other & such it's usually pairing behavior. Pairing angels test each other to see if the other is a suitable mate. You still need to keep an eye out, sometimes this aggression can get pretty brutal. Angels have been known to kill their partner, sometimes out of the blue for no apparent reason. One of the two has probably chosen that area as a suitable spawning spot, and is letting the other one know they like it.

Territorial aggression without pairing involved usually means the fish seem incompatable, except at feeding time. One or the other will be more dominant, and chase the other(s) away from their territory.

Either way, a divider is a good idea to keep on hand. Aggression can get out of hand at any time when you are dealing with cichlids.
