I will interject one last time, and an effort to help Camaro. I assume you are a car guy right (judging by your profile name, the camaro show)? You are doing what some people do with nice cars. Nicer cars take premium gas, and some people just put in unleaded, because there is no difference, it is just nicer gas right? Wrong. Premium gas engines have a higher compression ratio that requires higher octane. Put in unleaded gas, will you notice a difference if you do it once? Probably not. But over time, yes it will destroy your engine. Like this, will your fish be okay this week? probably, but as those fish grow, there will be fighting, death, and unhappiness of your fish being in tanks too small for them.
Another example, say you want to race your Camaro on the drag strip. But you put a supercharger in it to make it faster. The guy who sold it to you at a high price says it will be fine, thats all you need. Get to the track and race it on the dragstrip. What happens? The rear wheels fall off, brakes burn up, and you crash. Why? Your car guy did not bother telling you you need wider wheels in the back, and bigger brakes (among other things) to handle the extra power the stock car was not intended to do. Your tank is not meant for the fish you have, like the car.
On this forum we want to help, and can only help if you want it. Over time, people will start ignoring you because, "What's the point? He won't listen anyways." Like I said in my first post to you, we do not get compensated for our advice to you. They do (fish store), quite handsomely to boot. The faster you realize they are enabling your addiction for new fish and ruining your good looking tank, the faster you can get on track. Just think about what we all have said to you. If we all are in unison saying you are wrong, then maybe we are right. And we do not know each other either, all from different states (and countries). But we all agree on this topic. I hope this helps. I will be gone for the next week swimming in the Caribbean with other fish, so if you PM me any questions and I do not respond, thats why.
