Cardinal tetras
After a week since the quarantine aquarium’s start-up, I started considering buying next fish. On Saturday 21/1, I bought five Cardinal tetras (Paracheirodon axelrodi) andtwo Angelfish (Pterophyllum scalare) of the koi and zebra type in the Super Zoo store in Břeclav. At home, I put them into the quarantine aquarium.
In the meantime, one corydora died. Then, the last Electric blue ram cichlid (Mikrogeophagus ramirezi electric blue) started breathing fast and was staying close to the water level. I measured the NO2, but the values were in order. I didn’t find the fish next day. I noticed that one of the Angelfish (smokey) had something like a worm on the head. So, the symptoms were: fast breathing (choking) fish and visual contact with an object on the fish’s skin. I found on internet, that it could be a fluke (Dactylogyrus, Gyrodactylus). I immediately applied the eSha 2000 treatment. It is applied for at least three days. In the following day, the thing disappeared from that Angelfish’s head. But I kept applying the treatment until Sunday. A disease that probably got the aquarium from some store. Again confirmation of how important it is to keep the rules: 1. Quarantine after buying fish. 2. Take fish from the trustworthy sources.
No symptoms appeared on the fish in the quarantine aquarium, so I decided to move them to the main aquarium on Sunday in the afternoon. I took a vessel and I filled it with the water from the main aquarium. First, I caught the two new Angelfish putting them into that vessel. Then, I slowly immersed the vessel into the main aquarium and let the angelfish go out. The inter-step of the vessel with the main aquarium water was undertaken to minimize the risk of getting the quarantine aquarium water into the main aquarium.
Then, I filled the vessel with the water from the main aquarium again and caught those five Cardinal tetras. When I let them in the main aquarium, the other fish started chasing them like a prey. I think, the worst were the Serpae tetras (Hyphessobrycon eques). Some angelfish bothered them too. After some time, they all calmed down and the Cardinal tetras started calmly swimming. They were alive in the following day. They got used to themselves.
