Hi Hetha, Great beginner dart frogs would be the bumblebee darts (Dendrobates Leucomelas) Blue dart frogs (Dendrobates Azereus) Yellow dart frogs (Phyllobates terribilis) Phantasmal darts (Epidobates antonyii) and dyeing dart frogs (Dendrobates Tinctorius). The usual rule of thumb for dart frogs is 5 gallons per frog, a 40 gallon can hold up to 8 frogs. The list for dart frog plants is VERY long but a few that i really like are philodendrons, bromeliads, creeping fig, pepperomia and pothos. If you do not want to breed them don't provide areas for them to deposit their eggs. Its always a great idea to quarantine your animals like what you listed up on your thread, You can keep an inch or two in a steralite tub with plant trimmings as a tank but ive never heard of people quarantine dart frogs.

Different temperatures and humidity will vary between species. There are many people on this forum that are experienced with many dart species
