I disagree with the silver dollar dithers as "tough". I have an epic thread on the wimpiest Jaguar cichlid on MFK refusing to defend itself against ANYTHING. Long story short after three failed attempts at housing the Jag with other fish I have it in a hospital tank recovering from injuries.
Petsmart has a $1 Silver Dollar sale going and I bought a couple. The hospital tank is also my QT tank. It is already medicated for the Jaguar, so I thought it would be perfect and solve two problems for me.
1. It would treat the two new silver dollars for parasites prior to being added to a community tank.
2. I was hoping that the Jaguar might gain a little much needed confidence back during feeding time and be able to successfuly "bully" the two silver dollars for food.
Well, I placed the two silver dollars ~ 2.5" in with the ~ 6" Jaguar. The Jaguar moved faster then I have ever seen him move. The first Silver dollar was killed within like 2 seconds, and before I could even get the net back into the tank to salvage the second, the jag killed it too.
They did NOT get eaten, and I will get replacements today, but they did not last a total of 10 seconds with the worlds most timid 6" Jaguar!
