Hey!
I will try to answer all of your questions.. if I don't get it all, or you need more info... let me know. I don't check this forum but a few times a week, so if you need it fast, you can always drop me an email - bogart6868@aol.com
Some RETF's are more active then others.. and there is certainly a variance in size even for the same sex (I have some males that 1/2 inch longer than others, and more drastic differences in females. I would not worry about one getter larger than other so much. What you need to do is watch their weights. Make sure that they are not dropping weight. As long as each has good body weight, they should be fine. If your worried about their activity, mist the tank really heavily right before lights out.. this should kick em into gear a bit and get them moving about.
As for the spot, I would have see it to know what it is.. mine sometimes develop freckles as they mature.. Green spots sometimes can be a bad thing though.. Can you get a good pic of it for me? (email is above if that is easier for you to get it to me). Let me know if you have done anything different as well (added something to the tank, changed temp, humidity etc.. anything that is different)
There are lots of gnat like critters that can develop in or around tanks.. most are harmless to the animals, and more of a pain in our butts than anything. There are a couple of ways you can help to control this.. fly paper outside of the tank will help, or an open can of coke that is about 1/2 full will usually attract them and drown them. Either way, you don't want to use a chemical to get rid of them, which means it will take a little time to clean up the entire population.
As for thefrog, I am not sure what is going on, and really have nothing to do with the admin side of things. All I would be able to do would to send a new email. I know they had some trouble with some of the accounts and people getting locked out. That is fixed now, but not all of the accounts were reset. Beyond that, the admin is traveling alot right now, and I am not sure the mods can do anything about it. If I were you, I would simply create a new account and have at it. I am sure it nothing against you specifically and simply a technical glitch.
I am jealous.. I don't have a PETCO near me.. so I missed the sale completely.. congrats on the find though.. hex's that big can be turned into great vivs!! I like the size of that tank.
As for my opinion on frogs.. I love both whites and RETF's. Personally, RETF's are one of my favorite of the tree frogs. That said, whites make great pets too. Both are different in terms of care requirements, and both seem to have different personalities to a degree. As far as activity level is concerned, to me atleast, it actually seems to vary w/ individual frogs and not be based on species. Basically though, in the long run, it is completely up to you.. if you want whites, go that way. The different forums or groups you talk with will each have their favorites. Keep in mind though, alot of times people will champion one species, while having little to no experience with anything else out there, and whites are certainly one of the most commonly kept animals in the hobby.
All of that said, it ultimately boils down to your taste. I like variety.. So I would more than likely keep the retf's together, and get something different for the 2nd tank. Also, while wtf's are certainly a great choice, keep in mind that there are a lot of other types of frogs out there besides the whites and red eyes. If you can keep retf's, more than likely adding dart frogs to your collection would not be hard to do at all. (would mean you need fruit flies, but would give you frogs that are active during the day and you can watch and enjoy during normal hours). Also, there are several other tree frogs that are rewarding and very interesting to keep.. clowns, tiger legged monkey frogs, waxy monkey frogs just to name a few.
Just keep in mind, many of them are different in terms of care requirements, but they aren't really hard if you set the tanks up correctly and are prepared for them. The only hard part is finding correct information to use as your guideline.
I know I did not help w/ whites-retf debate, if anything probably created more questions? But it really is completely up to you. If you have direct questions about any of em that help you decide, don't hesitate to ask..
Hope all is well!
