nannacara advice needed please

[Luco]

Hi,

I had a pair of nannacara anomala and they were fine together for 3 or 4 months. Then one day I noticed that the male was looking a bit beaten up. I never witnessed any attacks against him but when watching the tank one moment he was definately moving away from the female and then an hour later they were side by side. So I couldn't really work out what was going on and assumed all was OK. Bad assumption. The next day one of his pectoral fins was missing along with a few scales and he really looked battered.

I removed the female to a spare tank but the male died about 2 days later. The female is back in the main tank and all is peaceful.

The question I would like to ask the experienced fish keepers here is "is her behaviour likely to be the same to all males or do you think it's OK to a new one?"

Some info on my tank - 180 litres (approx 44 gallons) I metre (3ft 3in) long. small caves at either end, some flat stones, a big lump of bog wood in the middle and planted with amazon swords along the back so plenty of hiding places and sight blocks. Other inhabitants are Cardinals, Otos, Sterbai and my out of place Cherry Barbs.

Cheers

Two possible answers. Both stem from spawn activity. Most likely is that you removed wrong fish and lost spawn. Female golden eyes will often become aggressive with males after spawning.
Second is that the cherry barbs are actually the culprits. Females usually go for eyes not find and scales. Cherry barbs are egg thrives and defend the school aggressively.
One additional note, golden eyes will sometimes kill ages eaters and corys. I have even had them to attack plecos. They do not like catfish.
