Well I'm not in the US and shipping livestock here is quite different. Despite that, Between shipping supplies and courier costs for next morning arrival, I find it a bit skeptical that $20 would cover it. But this topic is null and void.
My intention is not to cover all his expenses but to contribute towards them. As I see it the bottom line is the fish is unhealthy, and it's his fault. He was going to sell it for $50.00 in its current state, and it's not worth anywhere near that. As a responsible fishowner the needs of the fish should outweigh any other concern. If he walked into a LFS with that fish he would get laughed at expecting money/credit for it. I dont need or really want the fish but I will take it and nurse it back to health (an endeavor that will cost more than $50.00 if it needs meds), it will also require a tank for him alone. So noone will make a profit on the transaction.
A tank doesn't cycle. A filter does. If hes got sufficient cycled filters to run on a 180 then he can move everything over and used use some Stability to promote more growth. I'm not going to comment on something that I don't know about beyond that though.
Stating "a tank doesnt cycle, a filter does", is a matter of semantics and argumentative. A filter is a part of the system as is the tank 1 without the other is useless in relation to the system. Additionally, the beneficial bacteria that is the end result of cycling is not only in the filter but the water, and the hard surfaces within the tank thusly the whole tank cycles.
Since there is no response to my inquiry about how he was going to set up the new tank i will leave that alone as well.
Knowledge gained has taught me that not everyone possesses sufficient common sense.
