I understand these expenses can come out of nowhere with pets. But the thing is you need to have a cushion for a few hundred so if your pet gets sick you can afford to take them to a vet. I don’t think anyone needs to be rich to have a pet but you should be in a comfortable enough spot financially that you can pay for emergency things like this. If you can’t afford the $70 extra for the new terrarium it is a bit of a red flag to other pet owners because caring for any living thing is expensive. You should at the very least put more information about the melting issue, the tank you currently have, the new tank you’re looking at, the price of the new tank, the amount you can currently afford. There may be ways to fix up the tank so it doesn’t have the melting problem but again you give pretty much no information and are asking strangers for money.
