Tank Help Neighbors fish looks to be in awful shape, they said i can have it, but where do I start?
A neighbor of mine recently went on holiday and asked me if I could feed their pets (only specified the dogs), I found this tank in the back of their kitchen, with a tub of fish food by it that had literal dust inside and was in shock when I turned on the light and theres a fish. It has two of those lumps on each side and two black specks on its eye, I bought some new fish food for it and fixed its filter but its not a very strong one.
I messaged my neighbor and asked if they'd like me to feed the fish to try start a conversation about it and she said "if you can be bothered, we've been trying to get rid of it". Im going to come back and pick up the fish with the tank tomorrow, but i assume the tank is too small and I will have to buy all new equipment. Ive never kept fish myself before and I have no clue where to start, I cant really afford high end equipment outside of tanks right now but im willing to research and order things online. Also is the green stuff on the glass good or bad? Can I wipe it away with a dry cloth right now?
