The Spectacular Acarichthys heckelii

If you are into SA cichlids of the larger variety, then this species is a "must have" ...the incredible Acarichthys heckelii or Threadfin Acara. For sheer beauty, it is unsurpassed by few other cichlids. I presently am raising six, and these are about a year old, and pushing 6". They are very compatible with Geophagus / Satanoperca and I presently have them housed with nine Geophagus winemilleri. I want to share a few images of this impressive "jewel" of a species.

I hear they are a tad more aggressive than most eartheaters?

They can be rougher than most geos once maturity is reached. In my experience in the past, they never killed one another. With my latest six, there is one that is becoming dominant but they are in a somewhat crowded condition with good water flow, so nothing really serious transpires. Here is a posting from another aquarist ( 'duanes') from my MFK thread relating his experiences.
"Mine went into spawning mode a couple months ago, digging pits, and in the process started killing each other. I started with 5, three years ago, in the last 3 months, down to one. I had always heard a very large tank is needed once spawning begins, seems my 6ft 150 gal is not adequate. The aggression is very subtle, hardly noticeable unless I watch very slowly. Starts with just a scale or 2 missing on the head, then within a day or 2, I would find a corpse. I figured best case scenario, might be 3 dead, and I'd end up with a pair, had a pair going, little more digging, now down to one. Think it will end up at next months fish auction."

Amazing fish and nice pics.

I loved mine but I also found them to be fairly aggressive as young adults. I ended up with just one.

Hey Evan,
You're not the first person to have had that experience. It seems to be quite common. Mine have never gone to the point of killing one another, but some dominant bullying has occurred. I have mine in fairly crowded conditions, with a strong current to keep aggression down. Seems to be working so far.

Finding the disagree-ability of the heckelii quite odd here. I've got 7 of them in with 6 rh taps in a 125gallon atm. I got them when they were about 1.5-2" so that was back in February this year or so; my largest one is about 6" now with quite a few round 5" They seem pretty docile for the most part. My RH's who are starting to spawn are far more aggro than the heckelii.

At what point did the heckelii start becoming so disruptive?

I'm on the exact time line as you and lost one. My understanding is that they are slow to mature and don't start breeding until 2-3 years old and this is when poop hits the fan.
