Never mind, just noticed you have a 15 gallon.You can try Belonesox belizanus…Predatory Fins had them in stock a while back. They are piscivorous and nasty and don’t get too big
The OP was wise enough to first ask advice on this forum, so i doubt he will make a decision of stuffing large fish into small tanks. Most of time people stuff their tanks with inappropriate fish, encounter losses and then come here asking for help. But as you can see, OP is different. Hopefully he won't do such aa thing, so i advice you do not mock him.Lol, here's yet another recipe for disaster. Next question will be: "I have two Oscars, an Arrowanna, two Delhezi's, and a Pleco, in my 15 gallon tank and they appear to be dying. What could be the problem?" It's the natural progression of the question.
I agree, the response was harsh. I've been at this for a long time, and if I've learned anything when asked questions like this one, it's that when someone is determined to have carnivorous fish(or any other type of fish with specialized needs), they're having them regardless of the conditions they'll be kept in. Every time. It's the equivalent of saying "I want a snake, I've never had one, and I want a Monocled Cobra. How do I not get Bitten?" There's a difference between seeking advice, and seeking validation. This question sounds typical of the latter, not the former. And as a result, an intelligent, sentient creature will suffer needlessly.The OP was wise enough to first ask advice on this forum, so i doubt he will make a decision of stuffing large fish into small tanks.
