Hi guys! Is it ok to put just one pair Nicaraguensis cichlid in 110x50x50cm (43,3x19,7x19,7), 250l (65 gallon) aquarium? Tnx




Tnx dude a lot... Do you think it is a better choice is Gymnogeophagus Balzanii? Or some other fish that grows around 7" to 8". Heros, Satanoperca...A young pair with some growing to do may work a while.
Large old males can get a bit aggressive in that size space.
I kept a young compatible pair in a 75 gal for a little over a year, but it seemed necessary to move them to 125 (to me) when the male hit about 7"
They spawned several times in the 75and raised many fry.
Just an aside, I wouldn't;t keep any other cichlids with them, but geographically correct live bearers like swordtails or Gambusia would work well, util they spawn.

Hello again! Sorry I'm boring, but I see you giving information from personal experience. That it might be possible to put a pair of Heros Rotkeil in this tank? Since they grow up to 8 inches? Tnx...Balzani will work well in that size tank (maybe for life), they seem not quite as territorial in smaller spaces, more bluff than overt aggression.
And with geographically appropriate Buenos Aires tetras, and southern South American cool water Cory's as dithers, in a room temp tank, it would be a nice look.

The rule of thumb I use for my own tanks is that cichlids need at least 10 gallons per inch once they are fully grown adults.Hello again!

Why does Hecklii then all sites recommend even a larger liter than one pair of Nicaraguensis, grow smaller and I don’t see them being more aggressive than Nicaraguensis? in an aquarium of these sizes 43.3x19.7x19.7 I have been holding one pair of Sajice for 2 years (male 5", female 2,5") and I put 6 young Meeki to set aside a pair. i won't change that for a long time. Honestly, I also practice making the aquarium larger than the suggested sizes found online. so I don't even care that they spawn, how much I care that it is as phenomenal for them as it is for Sajica now (4 spawning in 4 months and the colors are phenomenal). But I'm looking for some list of larger fish, which I would keep with a pair and a school of Xiphophorus if it's CA or some tetras if SA is a biotope....The rule of thumb I use for my own tanks is that cichlids need at least 10 gallons per inch once they are fully grown adults.
I realize many other aquarists seem to be less generous with space.
For 8" adult severums I consider a 55 as only a grow out tank, and at least 30 gallons to small for adults.
The nicaraguese you mentioned average about 7"as adults, that's why I mentioned a 75gal
So IMO, a 55 is only temporary for any cichlid that reaches over 5.5 inches.
I also count in height and width of fish when considering those larger species.
So to me a couple 10" L oscars, that are 6" tall, and 3" wide would need about 180 gallons minimum.
But as 15" adults it might be a bit wimpy.
