Would you like to come over to my house and see my fish? They're all living happily, acting completely normal and they're fine. They may not have 100% IDEAL conditions but come on, neither do their natural environments 100% of the time. I know everything you just pointed out (which was quite rudely posted in a thread that it had nothing to do with, would have been better addressed in a pm), and also think it's stupid to stereotype fish personalities. The bettas are fine with each other, one of the females has some fin shreddage from the pet store, as does the male.. but it's been growing back over the last few months.. no new shreddage AT ALL. I've never seen fish that happy. The koi are tiny, and only in a tank until I can find them a new home (I took them from a friend that needed to get rid of some).. they're also very happy, and growing back some scales they had lost in the pond. The Jack Dempsey was less than an inch long when I got him and was being beaten up in the JD tank at wal mart so I took him, but he was too small to put in the community tank so he's in the small tank for now until he grows up a bit (another couple weeks and he'll go in the community tank). When he outgrows the community tank he's currently in he'll either go in the tank with the Oscar (if they get along) or if they don't get along or the Oscar's outgrown that tank already I'll get a bigger one and either put them both in the big one or get the JD a buddy and put them in the tank the O's in now. Hmm what else did you complain about? Oh yea, the blue zebra cichlid.. he's the most passive fish in that tank, stays in his cave most of the time, doesn't bug anybody.. don't see that changing as I've had him for 6 months and he's been like that the entire time. The electric blue ahli is a bit of a jerk but doesn't hurt anybody. I'm slowly building up the foliage in the tank and he's becoming less of a jerk as I put more plants in. Both the lobsters are perfectly fine. The really blue one in the community tank has only shed his shell once that I've noticed, but he stayed under his rock and ate it and nobody's ever bugged him. The other one is quite large now, he's shed his shell a couple times that I've seen and again nobody's bothered him. He had one claw missing when I got him because he tried to eat a clam, but that's all grown back now and he tries to pinch the other fishes with it sometimes but he always misses because he's too slow. It's funny actually. Hmm what else was there.. oh yea the goldfish.. they were supposed to be food, and they survived somehow and are growing quite large (they'll probably go with the koi whenever I can find a pond for them), eating everything. If they die, they die.. that's what they were supposed to do anyways. I'm not concerned about their tank specifics. The irridescent sharks (which you strangely didn't mention, but I just noticed someone else did after you) are being re-homed soon. Somehow even though I researched them I managed to find all the misinformed sites that said they only get about 6 inches long. For now they're doing great though, they're quite small still, and very dark. Basically the only one I'm not sure about is the plecos... I know they get too big, and we'll probably end up bringing them back to the fish store when they do (they have a huge tank with a bunch of big plecos that people bring back).
Like I said above, you didn't say anything I didn't already know.. I KNOW I don't have ideal parameters for all fish in the tank, but they're all doing fine. They're growing, eating, playing, they all get along. I inspect my fish daily (several times a day) for any damage, strange behaviour, etc.. and if anything is ever unusual I take the fish back immediately. I've only had to take back one Oscar so far, I bought it to keep my other O company but the ahli kept chasing it into a corner (like I said, he's a bit of a jerk), so rather than risk anything happening to it I took it back. I would have had to upgrade too quick anyways having 2 Oscars, those buggers grow like weeds!
My offer still stands, anyone who would like to stop by and see how well my fish get along, you're more than welcome. Stay as long as you'd like, see for yourself, they're all happy and healthy.
I'm also surprised you didn't mention anything about the convicts. Don't you know they're apparently viciously aggressive? They actually just laid eggs for the 3rd time, they protect their corner but don't attack the other fish even if they come near.. just kind of chase them away. The other fishes get the point real quick.
That's all I have to say. I know my fish, you don't. It's rude to post stuff like this in people's threads that are completely unrelated. It looks as if you're just trying to show off your "fish knowledge." Keep it in a pm or keep it to yourself.
