Hello! I'm a new user to this forum. I've never owned frogs (my mom owned some Fire Belly Toads when I was younger) but other than that I've had no prior experience with these loveable creatures. So as a newbie I have some questions that I hope you guys can answer!I recently received a gift of a 15 gallon terrarium with plenty of climbing room! I have a hydrometer, thermometer, heating pad for under the tank, a warming lamp, the works...First of all and really the most important in my opinion. The substrate. I received coconut fiber substrate. I've been reading mixed reviews on the stuff so I thought I'd come to a reliable source. Impaction is my worst fear. I don't want to be a new frog owner and have the little fellow die on me. So... is it safe? Insects will be prone to hide from being eaten so I don't want them to eat it and for it to harm them. Alternatively - what substrate would you recommend? I think impaction is my worst fear about this whole process.Secondly, I have a 50w Daylight Basking light. I don't think the bulb is appropriate for a Dumpy. From what I understand it's more for reptiles? Would this light do? Or should I go for something less? More? I also read that I should get the fellow a red or blue light to use at night to provide heat but doesn't let them think it's still day time. Any advice?Are there any other tricks/tips/advice that you would have to offer a new frog owner about my frog?Thank you so much for your time. I appreciate all the help and I hope to learn a lot from this forum and hopefully help others!
