sorry for your loss, i know how you feel on this one.
I'm currently stuck between a rock and hard place myself. I recently got a new 2nd hand tank for next to nothing in price. The only problem is i had to keep the fish, one of them in the tank is a sailfin plec which i cannot house at adult size.
He needs to go to a better home so he can have space to move once fully grown, but hes my favorite and seems to be good friends with my pictus cat (see my albums)
