In a 125 gallon its 2 Oscars, 3 Firemouths, 3 Gourami and 5 pikes. My plan was to see if I could get 2 of the pikes to pair and then sell the other 3 once everyone started getting big. I was told that it is extremely difficult to get pikes to breed in captivity, so I was just figuring on keeping the two that had the best color... Anyway, the pikes range from about 4" to 6" and this one is either the biggest or the 2nd biggest. I have not been doing anything to encourage breeding, because I have just set up the tank about a month ago and I've just been working on getting the water perfect and everything. As far as feeding, this pic was taken a good 4 hours after the last feeding which was not all that big. I feed staple pellets twice a day and color pellets twice a day and some minnows once a week. If they do spawn, it will be one of the times where it has nothing to do with what I'm doing, they just did it themselves, because I haven't been doing anything special!
