I bought a guppy and a neon tetra and put in a 1 gallon tank will this work? size of tank is only temporary.?

Defie "temporay". a guppie and one neon tetra should have at least 10 gallons. this is because they can get stressed out of there one gallon tank. U should not keep them in there no more than 7 days. At least get something bigger than 5 gallons. 10 gallons is way better for the guppie requries more space than a neon tetra.
