Compatibility issues

  • We are currently upgrading MFK. thanks! -neo
I agree with this, for a while anyway, but in time both the hetero and pearsei will significantly outgrow the metae and could turn the tables, just depends on whether they will realize their strength and potential.

No harm in trying I guess (option 1+2), but I doubt it would turn out well in the long term. Eventually the metae will reestablish its dominance. Rearranging decor is a strategy that can work when adding new fish because it allows all the inhabitants, including the new one(s), to set up territories from scratch (i.e., no home field advantage) - it prevents the newcomer from facing a disadvantage immediately upon arrival. However, in the end the territories will be set up based on dominance hierarchies. In your tank that means the metae will dominate (and it knows its place based on experience).

Un related but may be related... I changed out the gravel yesterday and havent seen any attacks probably more coincidence than anything else also fed some roamine lettuce the metae was doing her usual gaurding it. When I cam back from.running an errand the pearsei was chowing down and was showing aggression to the rainbows and heterospilus....

I personally think one of the keys with more aggressive cichlids, unless you really under stock them, is to have a larger number of them. I know this is often done more so by African keepers but I have had a lot of luck, even keeping unlikely combinations, using this method with SA/CA cichlids. If you don't have room for multiple bigger cichlids, get some more smaller ones like thorichthys, cryptoheros, etc. I think once you get over ten or so, it seems the oddly aggressive fish just isn't able to single out one specific fish as easily. As an example in my 155g I have a bunch of loaches and some catfish that are essentially dithers, and:

Firemouth
Thorichthys pasiones
Sajica
Spilurus
Convict
Cichlasoma dimerus
Australaheros oblongum
Blue acara
Guinacara sp
Geo Steiny
Geo iporangensis
Flier
Jack Dempsey
Angelfish
Festivum

So far they are doing super well and no one gets picked on. They are not all full size yet, so we will see what works long term, but most are sexually mature and haven't caused any problems.
 
Thanks quo but I wouldnt be comfortable stocking my tank loke that im sure it does work but once these fish are adults space would have to become an issue along with water quality....you must do tons of wc lol

Well i didn't mean you should do exactly the same amount/types of fish, I just meant as an example of smaller <6in fish that could work. I typically do 50% WC but I'll probably up that number as the fish grow bigger. Also the tank has a sump, so there is more water, and is below a window so I have tons of pothos, etc growing out of the top like crazy. I may eventually add an auto drip since I am already adding one to my 700g anyway.

I think you could easily add a handful of new fish like some of species I have, and it may be enough to distribute the aggression. IMO cichlids either need to be under stocked or over stocked (not in bio load, but numbers) so to speak.
 
Thanks quo I think your right but we'll see
