I want to save him!
I was in a local petshop yesterday. The guy who runs it is actually pretty good, by petshop standards. When he saw a sick goldfish in the (typically) overcrowded tank, he scooped the little guy out and isolated him in the plant tank, which is twice the size and has no other fish (the other guys were attacking him).
However, he also had a tank with coral blue dwarf gouramis, male swordtails and serpae tetras -all quite aggressive fish. The serpaes were mostly just bothering each other, the stupid little nippers (heaps of them had nipped fins), but the swords had basically declared war on the gouramis. Two were hiding behind the filter, one was fighting back and one had a wound on his side, most of his tail missing and smaller wounds around his head. I really want to go back and get him out of that tank, since he clearly can't fend for himself in there. The guy who runs the shop doesn't have any other isolation tanks.
Here's my dilemma: I don't really have anywhere to put him. I have my overcrowded sorority (moving to the 23 gallon in a few weeks where I won't be overstocked anymore), but he would fight with the girls, I presume, gouramis and bettas not being famous for getting on. I have my 3 gallon CRS tank, but that's too small and it's only 20 degrees celcius. I have my 5 gallon, but that's Odysseus's.
I also have an empty 5 gallon hex. It is too small for him, and I don't have permission to set it up. It does have a heater and a filter (I can do an instant cycle with borrowed media) but I'm not sure I have enough powerpoints to run it.
I suppose the logical conclusion is that I can't save him, but I hate having it within my power (I could do it if I just had permission!) and not being able to save him. :(
Maybe if he's still there/alive when I get the 23 gallon I'll consider it, although I'm supposed to be shutting down my 5 gallon when that happens.
Le sigh :(
