How many Cobras could I house in a 300gl??

It should work until the sabertooth grows large enough to eat the pike. Of course your pike will recognize that it's a top predator, so it will be a little more aggressive with the sabertooth, split fins and missing scales come to mind.

On a side note, pseudo-piranhas tend to show different behaviors depending on diet, based on my experience. If feed a nearly 100% herbivorus diet and kept with nonaggressive tankmates, they tend to be calm, peaceful inhabitants. When kept with aggressive tankmates and fed the 40+% protein diets we all tend to feed, they get mean, often bullying fish considered much more aggressive. It's well documented(mostly in reptiles) that animals fed excessive or foreign (red meat fed to white meat animals, warm-blooded protein fed to cold-blooded animals, etc.) protein sources act much like steroids. Food for thought(pardon the pun).

Dont know... I want to get another tankmate, but I have to choose it wisely

Thanks

Mark laid it down word for word. That really would be your best chance for a set up in all reality.

When I had my 300gal up and running I have four Crenicichla acutirostris in there. Even though acutes are generally more laid back and what not, there was still some aggression even in a tank of that size.

ChiefMojo has a 900gal tank, he was successfully able to keep multiple pairs of pikes in that size tank for a while. But even in a tank of that size he still had occassional problems with aggression.

Rich (Infinite Aquatics) has some Crenicichla sp. 'tapajos I' last time I checked, and for a wicked great price. Definitely recommend going with them. You will still want to get a group and have them grow out together in a larger tank, then as they start to pair off remove the others.
