Odd, I was told they were very aggressive when they bred. Thats good to know, I should be able to keep a semi peaceful tank with these guys in it as well..
I think it's obvious that ANY cichlid is going to be more aggressive when breeding, and I'm sure Spinos are no exception. That said, if individual spinos are less aggressive than individual rainbows, I think it's probably safe to say that breeding aggression by spinos is likely to be less than for breeding rainbows. Rainbows are always considered to be very mild on the cichlid aggression scale, so...

Also, you should be made aware that Spinos like to "hang" their eggs (or young, can't remember which) on plants, so you need to have "plants" in the tank.

There have been some posts on other sites talking about extreme aggression while breeding thus making a pair the sole workable inhabitants. However my research shows that they seem to be among the least aggressive cichlids. I have read about their breeding a bit and have read that the wigglers get attached to plant roots or stems as wigglers. They are also extremely small and may not be able to feed on BBS. They seem to feed off infusoria as well as other microscopic feeds located in plant structure. This may well be the reason they are not as popular in the hobby as they should be given their temperment and coloration. For those who have not seen them...

It seems they need dithers and possibly other cichlids around to breed well. Atleast according to what I have read. I'd like to know what other cichlids would go well. I am assuming I could do apistos but they like soft soft water and mine is naturally hard here. I'm not for all the work that is involved with softening water that much, besides according to most info available they like neutral to hard water. Opinions?
 
As an addition, one place that states that these can be an aggressive fish is CF.

"A smaller growing, absolutely beautifully colored cichlid. Adult coloration will be a combination of violet, purple and green to golden hues spread liberally throughout with black dots or 'sprinkles'. Females are distinguished by a smaller size from the larger, chunkier males. Individuals of this species will be a relatively peaceful cichlid in the aquarium. Beware of stocking a spawning pair in community tanks! They are very protective - aggressive - parents. A six foot long tank is recommended as the minimum size for keeping this cichlid as spawning pairs, in 'mixed' species community tanks. Stock with tank mates that are 'robust' and hardy in nature, but not so large in size they will just simply eat your pair!"

I'm finding this hard to believe based on my other reading.

On another note, Rainbows might be a great tankmate in a DIY 100g 4' long.

Opinions on any of this info?
 
Two comments: Firstly, the coloration of mine was distinctly a light purple, whereas the posted pic tends much more to brown. Secondly, it's really hard for me to imagine a breeding pair being so aggressive as to become a huge problem. If you DOUBLED the aggression of my individual, it STILL wouldn't be up to the aggression of my individual rainbow (although s/he was mostly bluff).
 
I think if I choose to get these and some rainbows, I will have a plant filter with emergents as well as a few emergents in the tank for hang down root structure. I've had no luck with completely aquatic plants bu then maybe I've just not tried hard enough. That,s and it's also an epoxy coated plywood tank. I'm not trusting roots to not try to grown through the epoxy. Maybe a few potted plants and some that I can attach to structure. As for color, here are a few different pics of the fish.

I sold two pairs of them before moving cross country. They're not aggressive as far as cichlids go. A pair of spilurum dominated them.

They're pretty fish and exhibit the purple undercolor when mature and happy. The bottom picture above captures the coloration pretty well.

I wouldn't call them either spectacular or outgoing. In 2-3 year mine were pushing 4" for males and 3" for females. They breed like rainbow cichlids...pretty good parents. They spawned with warm water changes and heavy feeding of flakes and pellets.

Of course I quit raising the offspring because no one wanted any...could hardly give away the 2"-ers. I guess they weren't the "in" fish at that moment.

And now they are one of the hardest to find central americans ... crazy how fish popularity cycles work.
