Hi everyone.
After all this time with no problems since the five footer was set up I've had a couple things happen in the last few days!
First off I noticed in the week that my Thread Fin Acara was acting out of sorts. Usually very active and very willing to feed he was hanging around one top corner of the tank looking glum. At times I've seen him have trouble kind of staying upright and moving as fluidly as he did. Also well off his food. He has no visible marks or signs of common aquarium illness so I am a little stumped as to why he was fine one day and not the next!
Before I go on, water conditions are- Nitrates, virtually zilch
Amonia, 0
Nitrite, 0
Ph, 5.5 (more acidic than I'd like)
Now, when I came home last night and went to have a look at how he was getting on, I realised the largest Choc (male) had a big white thing on one of his eyes, his head covered in tiny scars. And right before me he shot out and chased away the Severem and started lip locking with the Smaller Choc (I've always guessed female). It occurred to me then that maybe the thread fin's mysterious illness might be the result of coming a cropper from the Chocs behaviour and taking a knock, or even just stress from their activity. does anyone think this likely? I'm guessing the Chocs are courting?
I've just this minute watched them both pushing at each other head on and swim off to separate areas. that seems more territorial than breeding?
Cheers guys.
