Mature community tank, 30+ years running

Just wanted to share a couple of pictures of this mature aquarium.

The tank holds about 360 litres, run by two internal filters; one Eheim and one unidentified. The tank is heated by a Jäger heater.

This aquarium was bought second hand in 1980, it was moved once in the early eighties and had a leak once also in the early eighties. Apart from those disturbances the tank has been running since.

I would probably have chosen a different background and substrate today but has it been there for that long it can be there for while more.

The inhabitants have changed; the main difference has been if there has been Discus or Angelfish inhabiting the tank.

The stocking today:
5 Angelfish
around 100 Cardinal tetras
around 20 Platys
3 Bristlenoses

I was saddened not to find the 10-15 year old Banjo catfish I spotted last year, I hope it’s still around in there though.

The interior has been the same, the small piece of bogwood in the middle once took up 1/3 of the tank and the Anubias originated from one plant.

I really, really regret not having taken one photo of it per year as it would have been very cool to have seen the evolution of the tank. This is something ill try to do with other tanks from now on and that could be an idea for fishkeepers in general.

Ancistrus sp., sexing revisited

Ancistrus sp., females with bristles

It now turns out that I was right about the young female, one of the males however turned out to be a female which im very happy about.

In the end it seems that both males and females grow bristles quite early, it is however still possible to somewhat accurately sex the juveniles by the amount of bristle growth.

The females today:




















They still need to put on some weight but I am hopeful about getting some fry from these next year.
