Would you mind sharing photos of the tank please?I know it’s not the best situation for the Goldie, but the trough outside isn’t deep enough to stop from freezing all the way through in winter. I try to do 25-50% water changes every week. It’s a secondhand tank, so it’s got awful fluorescent black and neon gravel and fake plants. My New Years resolution was to figure out how to rescape it and replace the gravel with sand or fluval substrate or something similar to fluval, and add some sturdy plants. The Goldie was a cheap one from Petsmart and was already severely stunted when we got him two years ago.
All of the females but one have already had babies, and I’m not worried about more because, as you said the Goldie will eat them. Any surviving fry I will most likely rehome if they have any more.
I think the gourami might be better off in your care, but while remaining in the three gallon, with some floating and live plants, rather than in the larger but more exposed tank with a goldie and platies, which aren't fish that respect territories either.
Or, might be better not to try to save the gourami, and hope that someone else takes him, or get him, keep in the 3g temporarily, and rehome him yourself to someone with a more suitable set up.
Your heart is in the right place, @foxgirl158 ! I do really like that you want to adopt him, and that you're working with what you have. But sometimes you need to step back and consider whether it's really the right move or not. It might well be better not to try to adopt this particular fish only to move him to another set up that isn't right for him. But to focus on the changes you'll need to make for your current fish first. Obviously it's always your choice, just want to give my thoughts and encourage you to really consider whether it's the best move for all of the fish involved. We have to use our heads as well as our hearts. <3
@Essjay would love your thoughts!
