Anyone in the club ever keep Nandopsis islantum

It would make sense for 'Cichlasoma' istlantum to show a high amount of intraspecific aggression rather than interspecific aggression as it is the only cichlid native to the Balsas river system where it is endemic to, so there is no other cichlid they are naturally competing with.

I have a confession. I'm a cichlaholic.

I have kept a group of the, in a 45, to start, at about pinky fingernail size, by the time they were thumbnail size, I was left with only 1. Honestly they are a lot like the Grammode, but with the personality of a Amp. I sold mine, and it is by far my most regrettable fish mistake, I have spent years since looking for true ones (ACA a few years ago, there was some mistake and was was labeled as a Izzy, was Grammodes). Very agressive, and a perfect occupant if you want a single. (I do) Have not bred them, so no experence there, but a Damn Nice Central.

They get quite more aggressive than they are now. They are little b******s. You should call them 'Cichlasoma' istlantum with cichlasoma in parentheses as this fish currently does not have a proper genus described for it. Nandopsis was described and restricted to fish from the islands of Cuba, Dominican Republic, and Haiti that are all closely related to each other.

I would not recommend a tank smaller that 6 feet for these guys and like Chef Jimmy said, crowd them if you can to diffuse aggression a little bit. The more territories to break up sight lines the better. I've not bred them, but they will breed much smaller, around 4-5 inches. They are prone to bloat from stress. The best thing for that is keep the water at a stable temperature, lots of water changes, and try to get a little vegetable pellet or flake. It's not an easy fish to keep from its sensitivity as well as its aggression.

I've never kept these, but I've kept lots of fish like these.

I would keep them in a tank with lots of fish to keep them confused. Like a 55 or 75 with 20-30 nics or hrp.

If they are not a fish that has bloat issues I would keep them around 75 or 76 degrees. Cooler water will keep the aggression down.

So I picked up some Nandopsis islantum "Red" at the Rare fish auction,

I am amazed at the aggression level at such a small size 1- 2 inches.

How aggressive are these?

Anyone in the club have luck breeding them or keeping them? If so what size?

What conspecifics did you keep them with?

Again was just interested if anyone has kept them.
