parrot crisis! but i know you guys hate parrots but i need help

The two parrots you owned before may be paired up. They may need time to settle in, but if paired, the other parrot won't "fit in".

The fungus in the head wound is just from an infection. Maybe your water quality has declined? Maybe other stress was bothering him. He's dead and gone now, so I wouldn't worry about that. Just keep water in good condition. Treat wounds promptly with Melafix ( I buy the pond bottle - same stuff, just more concentrated)

Seperating it may be a good idea. It might let the new parrot establish its on territory. I wouldnt leave the other one in the net thing for to long though because it might stress it out and then when you let in out the new one might think that that one is a threat and then you owuld have more problems. Good luck!

how big are the fish? how big is the tank?

Yes how big is the tank? If it is a good enough size you could get many different fish as dithers. Just depends on what size tank you have and what you are interested in. Giant Danios would be good or regular sized ones if your parrots are not to big.

You want target fish, not dithers. Dither fish are used with fish like dwarf cichlids that are shy. The dithers swim in the open, giving the dwarfs confidence that no large predators are in the tank. Instinct tells them it's possible, so being in a tank does not take that out of their minds. They need the "all clear" signal from the dithers.

Target fish are fast tough fish that can also double as feeder fish if they get cornered. The common Australian rainbow fish, small convict cichlids, and giant danios are commonly used this way. Watch out with convicts. They can sometimes become competition instead of a target. They should be inexpensive and common as well as matched to the water qualities you are keeping your parrots in.

It's possible that the Jurupari died as a result of stress, if it was intimidated by the two parrots. The fungus infection would take advantage of its weakened immune system, since the spores for this are ubiquitous. In a small tank, there may not be room for a third fish. In that case, no matter what you add, the nature of the tank will bring those numbers back down to the capacity of the aquarium.

In my own experience, live feeders have only increased overall aggression between fish in a tank.

That's a good point, Sumpnfishy. Diet can affect aggressive behavior, especially feeders. With some of the large cichlids like red terrors the whole target idea seems to backfire. Having a target fish like a big pleco only seems to frustrate the more aggressive partner who takes it out on his mate. Tank size is a factor. Do we know yet how big this tank is?
