the species i would recomend is:
Phelsuma Madagascariensis Grandis.
espesially the High Reds. really beutifull animals. and they get quite large, about 25-30 cm. if you fill you tank with a bunch of nice plants, they will get along with 2 daily mistings and a temp gradient of 25 celsius at the bottom of the tank and 30 at the topp. some say that they need a basking spot to but i wouldent do that because it would raise the temperature over the limit of what is healthy.
these are probably the most common phelsuma on the market today.
Phelsuma Madagascariensis Kochi.
has almost the same requirements as the Grandis but it wants a tank a little dryer and warmer. they are unfortunely not that colourfull at all. this one is also pretty common at the market.
Phelsuma Madagascariensis Madagascariensis.
requiers a bit more humidity than the Grandis, but temperature is the same. several mistings a day requierd, dependig on tank. RH should be around 75%. this Phelsuma looks like the Grandis, The madagascariensis has different colour fields and and the spots/stripes are more orange then red. also common at the market.
the last one i recomend is
Phelsuma klemmeri.
this is one of the most beutifull daygeckos according to me.
BUT to think of before you get one: they are very flat, and dont become more than 13-14cm. so your tank must be 100% escapre free!
they are pretty easy to maintain. hotest area in tank about 28 celsius and 60-75% RH.
not as common as the other spicies but still pretty easy to find.
all of the above goes under 150$.
wish you all the luck with you new gecko!
