This is a direct copy and paste quote from the first time I mentioned the 4' deep tank.
"I have seen them in tanks 4' tall"
It says "seen". It does NOT say that I have had them in that size tank.
All I am saying is why limit them to such small tanks? I have seen them in much larger and they were fine, seemed better than ones I have seen kept in smaller tanks. I find it hard to believe that everyone would argue so hard against bigger tanks when there is so far no information indicating that such a tank would be harmful in any way.
I have seen them in these tanks that you guys are declaring inappropriate. You guys are saying that is wrong because articles and caresheets recommend otherwise.
I am not trying to insult anyone on here. I am sharing my direct experience with the species in question and everyone else is saying it is wrong 'because', with no information that actually shows theya re at all stressed in a tank deeper than 18".
The National Zoo has them in a tank about 4' deep. My first thought when I saw that tank was the same as all of yours. I thought that was way too deep for them to be swimming up and down all the time and that they must be stressed and try to hang out up top as much as possible. A couple were hanging out in places above the bottom, but most were on the bottom. I stopped to watch that tank for a while and watched them as they went up for air. It was actually quite impressive. They gracefully made their way up, gulped, and slowly descended back to the bottom. It seemed almost effortless and very natural. So yes, when someone claims that they need to be in no more than 18" of water, I have to say that my experience completely disagrees with that. Yes, many articles may recommend shallower tanks, but what are they basing that on? These frogs are amazing swimmers, they have no problem in deep water.
These are also animals with a high bioload and many keepers can easily let water quality drop more than it should. A larger tank will help with that. It does not mean that if they get a bigger tank they can slack off on their care. It means that if life happens and they miss a water change or two, the water quality will still be better than it would in a smaller tank.
Bigger is always better. Do you need the deepest tank possible? Absolutely not. If you want to get a 30breeder as opposed to a 29, great.
Do they need to be kept in no more than 18" of water? No. In my experience I have seen and had numerous tanks with them in water of over 18" and have not seen a single indicator of stress in any of these tanks.
Please, if you have information to support that they can't be in deeper water I would be more than happy to read it. But if no one has had or read any threads on any forum about cases where these frogs were kept in water over 18" and there were issues from the depth, why keep taking articles' word for it unquestioned? Just because it is suggested in multiple articles does not make it a fact. The numemrous cases I have seen show this.
I am not trying to argue with anyone or about anything just for the sake of it. I simply question and try and correct information I see that in my experience is not true.
