The computer is working again… the motherboard died!
The new tanks added reached a temperature of 22 degrees C, without any heating, so I had to add internal Visitherm 200 watt heaters to each tanks, to get the temperature to 26 degrees C, I also had three spare 18 watt lighting units and tubes, so I’ve also added these.
I’ve since added two Serpae tetras Hyphessobrycon eques, two Zebra Danios Danio rerio to two of the tanks to help mature them.
The remaining tanks is currently being used as a quarantine tank for my Wild Male Silver Angel fish Pterophyllum scalare which could be a Peruvian Pterophyllum scalare which has developed a nasty ulcer on the shoulder near the dorsal fin, I noticed it in the display tank, and thought at first it was an injury from another fish, but has got larger, I’ve been treating with Melafix for over 7 days, but I don’t think it’s getting any better. The fish is still alert, eating well, and doesn’t seem to be in any distress, there’s no swelling, blood or fungus, it’s very odd.
