The heater will be about $7 at Walmart. You can buy a hospital tank of 2.5 gal. for under $20. You can also try checking craigslist in your area for a small size tank for a hospital tank between 2-5 gal. I like the 5 gal. as I have angelfish and they would not fit in a tiny 2.5 gal once they grow bigger and get sick. I have a 2.5 gal hospital tank also for smaller sick fish. I always keep a couple small fish in the tank just to keep it cycled. dwarf shrimps are ok or a a catfish. You will have to remove them if you add medication in these tanks as it would not be good for the shrimps although Pirmafix & Melafix is safe for shrimps or snails and baby fish. I keep both of these medications on hand with some Ich cure and aquarium salt on hand for any sick fish.
