Hi,
I got a trio of these a few weeks ago and have them in a 36" long planted tank with plenty of caves and driftwood. This is an established tank with soft water and a neutral pH.
I have had some up's and down's with these guys in a short time /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> ! I have never kept west african dwarf cichlids before but have kept many other diverse species successfully.
These are really neat fish and quite beautiful!

The males as expected, dominates the two females. I noticed yesterday one of the females displaying for the male. She looks ripe for spawning. I also noticed him nipping at her under belly, not sure if it was aggression or ...?
So today the same female has a bit of tattered fins and I have observed him aggressively chasing her. The other female is hiding in a cave and I can't tell if she has been harrassed also.
I caught the female and have her isolated in the tank with a breeder net. I'm not certain what to do? This is the second time in two weeks I had to seperate them to protect the female.
On another forum a member spoke of how his male killed the females. I could possibly find a home for her in another one of my tanks, but she would not have a species companion. Then the question is; will the male turn his aggression towards the other female? I wonder what is the success rate for keeping parilus pairs or trios? My LFS were I purchased them is no help.

Any tips appreciated!

Tony

Hi, I haven't kept this specific dwarf but have had a couple of others. I found that once a pair formed then the others was bullied, especially if eggs/fry were present.
Is there any other fish in the aquarium apart from the Parilus?
You say you have had some troubles, could you post your water params and details of the problems /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Hey tbone. I´ve not kept N. parilus but did have some success with N. transvestitus a while back. The males of this species were very vicious too. I bought 8 of them, 3 of which turned out to be males but pretty soon I had only a single male in the tank as he just battered the others. He was also very aggressive towards the females unless spawning with one of them.

The problem is that Nanochromis only seem to form weak, temporary pair bonds. Spawning is inititated by the female so it sounds as though your lady was ready to spawn but the male wasn´t. I would suggest reintroducing her when she´s recovered, while keeping an eye on the second female. Exactly how much cover is in the tank? The one I used was 55 gallons and almost completely filled with bogwood. I´ve also read of successes using bare tanks and loads of fish, crowding them as is usually recommended for Mbuna. Hope that helps and best of luck! /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Water in this tank measures: Nitrate 10 ppm, Nitrite 0 ppm, Ammonia 0 ppm, gH 25 ppm, dH 40 ppm (3 dH) and pH 7.0. Temperature 79* F. I perform WC's weekly.
I have been conditioning this tank with a peat moss extract that I made. There is moderate amounts of caves, plants and driftwood. I am going to add more soon to provide more hiding spots.
I believe the water chemisty is okay and coverage is okay also, there's always room for improvement though.
For tank mates, I have Iriatherina werneri & Puntius Rhomboocellatus in with them. The Parilus ignore these guys so far.
What I mean about "trouble" is the aggression the male is showing towards the females.
The only thing I can think of is to add more females to spread out the aggression. The male spends a lot of time roaming looking for the females to harrass. I don't feel confident that adding more females will work, it would end up being an expensive mistake.
This is a challenge for sure...

I wouldn´t be too afraid of adding more females if you can provide sufficient cover Tony. Can you get a picture of the set-up?

i do agree that more females will spread the aggression about so preventing a few from being harassed as much. with plenty of cover, he may settle down. perhaps he is sourcing a female for pairing up with.? just a thought.

Hi,
I will try to get a photo of the setup, the wife has the camera for work.

I decided not to add more females and I'm going to move the lone female to another tank.

Last night, to my amazement, the pair were hanging out together and the male was not showing aggression towards her. She is displaying for him and doing her dance and the male seems to respond by nipping at her underbelly. They actually seem like a pair! If this continues, I will be happy!

I tend to be a bit over protective with my fish. I have a hard time sitting back and letting one of my fish get killed. This usually leads me to buy another tank, but this time I can't, the wife will kill me! I only have six tanks. If it was up to me I'd get a couple more big ones.

Thanks all for the tips! I will keep up dating this thread.

Regards,
Tony

That sounds very promising indeed Tony! Do keep us updated and keep a close eye on the pair as in my experience Nanochromis males can turn nasty quite randomly at times. Good luck /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
