First i want to say that i'm quite lucky here. I posted a thread awhile ago stating i needed to buy a 5 gallon tank. Ended up that it's a good thing to wait for one when you don't really have the money
. My uncle gave me a free 5 gallon tank that "might" have a broken filter. I still have to look at it. I'm not really sure what to put in this tank though. I was thinking of a betta and maybe my 2 cories in my 10 gallon that are left from the heat massacre.
Also i was wondering if there are any types of fish that work with any type of goldfish. My goldfishes are dying out one by one it seems now, so when spring comes i'm putting the last few in my pond with my koi (is that a good idea or can they die from that? the ones that are left are very hardy). So out of curiosity, are they any fish that work with goldfish in the same tank?
