They are all nasty fish as far as I'm concerned - actually, having wached pyrannas eat they aren't anything like that aggressive. All were mistakes of the fishing company - I was trying to get two white Gourami's they had and I had never seen one before. Apparently, neither had they because they kept shipping full size Blue Gourami's. The 5th one is Tiger Gourami and I must have made that mistake but I would not have ordered her knowing her size (nearing 8 inches - I told her tonight that she's just fed up and claustrophobic. The sixth one was sold to me when I was first shopping for Gourami's - and he told me this fish is the only Gourami they had (nothing was labled), now the man has been in the fish business for 40 yrs I think he knows a cichlid from a gourami and she will approach 1 ft long unless she stop growing. I call her "Hot lips" because her lips are so big. And she was only $8 or $12 - he was just barely ripping me off but he knew what he was doing. Bought some other fish from him and ALL of them died. Did a water change in case there was a problem (there wasn't) and they refused to take them back because I had told them I had done a water change and they wanted a water sample at the time of all the fishes deaths. Damn local store has nothing written out plus they rip you off - you don't go back but I needed some black gravel really badly so I sent my assistant over there (Pet's Mart had like NO GRAVEL or SAND, same with PETCO.) But Mr Ripoff did - so we bought that and ordered a second bag from Amazon.
If I offered to ship free - it would have to be overnight in a cooler with ice or heat pack depending on where they are going - that costs about $40-50, I know because I buy fish that way all the time since we have nothing here. I don't do Craig's List alone in this city - we've had so many criminals, even a cop got shot by the buyer of the guns he was selling - CRAZY. But I think they just aren't interesting enough and they are so big - nobody wants to provide room for them. If you bought one they'd only be about $8.99 a fish. I'm really shocked they are breeding since the tank conditions are far from optimal and I always thought the tank had to be a great set up before they'd reproduce. I''ve got a M and F Lemon Yellow Bristlenose Pleco and a M and F Tomasi Pleco and they won't have anything to do with each other. Those would be easy to sell.
