Albino African Clawed Frog swimming
upside-down - 07/13/08
I have three African Clawed Frogs in a 29 gallon tank. They share the
space with two spotted Rafael's. In the last two weeks my Albino ACF started
acting weird and started swimming a little weird. I was away on vacation for
the last week and changed 1/3rd the tanks water before leaving. Upon coming
home I found my Albino friend upside-down on the bottom of the tank. I
grabbed a net to take what I thought was my dead frog out of the tank only
to find that my frog was very much alive.
<Well that's good news at least. In any event, your first stop here would be
to test the water, at minimum the nitrite level. Almost all "sudden
disasters" in aquaria come down to water quality, and if you've been away,
there's every possibility that something went wrong in this regard, and the
livestock got sick. I'll put aside for now my general observation that fish
and amphibians don't mix.>
Watching her over the last day I see that she still has a lot of energy and
a very strong kick, but she has trouble swimming right-side up.
<Not really a symptom of any one thing.>
My frog spends a lot of time in the corner wedged between a gravel filter
tube and the side of the tank. I'm thinking she is doing this so as to
breath air without trying to figure out which way is up. I also sometimes
still find her upside-down on the aquarium bottom. I'm pretty sure she is
not eating her regular diet of live crickets and recently added
freeze-dried tube worms (with no luck either.)
<Do remember that these animals won't thrive on a single food item. Frozen
bloodworms and live earthworms would both make excellent additions to the
diet of these frogs. Freeze-dried foods are, in my opinion, a waste of
money. Moreover, not all animals eat them (and none of mine ever seemed to
enjoy them).>
The other two ACFs, a male and a female, both seem fine, as do the spotted
Rafael's. The only major tank change I made before heading out on vacation
was taking old plants that looked like they were dying, and replaced them
with new ones. (The kind of live plants that come in a plastic container
with a gelatin in the roots that keeps them alive for a while.
<Never seen these. Must be something particular to your country. In any
case, being protein-based, gelatin decays under water and adds to the
nitrogenous wastes in the system. Could very easily have caused an
ammonia/nitrite crisis in your absence.>
These plants have not shared space with any other water animals.) I have two
filters running. The pH is often high and I find I am regularly using pH
Down to bring the pH level more in line with where it should be.
<Arggghhh!!! Lesson #1 - Don't change the pH unless you also change the
hardness. One of the most common mistakes inexperienced aquarists make is to
assume that a fish "wants" a certain pH. They do not. Fish don't really care
about the pH. What they need is for the pH to be stable. Beyond that, most
freshwater species will adapt to anything within the range pH 6-8. What fish
DO care about is hardness. So when you have an Amazonian fish and you read
it comes from "soft, acidic water", that means your job is to reduce the
hardness. Do that, and the pH will go down by itself (sort of, anyway).
Change the pH using buffering potions without changing the hardness and all
you're doing is creating an unstable environment. No fish wants to live in
hard but acidic water overloaded with buffering agents. Blech! If your water
is hard and alkaline (basic), then don't worry, you're fish don't care. I
think the reason inexperienced aquarists change the pH is because it seems
easy to do, especially when compared with softening water using rainwater or
an RO filter. But that easiness is illusory! By the same token, this is why
so-called soft water from a domestic water softener is bad for fishkeeping
-- it's chemical composition is all wrong for most fish, despite the fact it
is called "soft water" and so sounds like the stuff you get in the Amazon.
It most certainly IS NOT like the stuff in the Amazon!>
I also changed another 1/3rd of the water in the tank yesterday just in
case.
<Change more. After a crisis, change 50% immediately, and then another 50%
6-12 hours later.>
My Albino friend is about 2 years old and does not have any skin problems,
bloatedness, or red anywhere on its body. I've also heard that female frogs
sometimes swim upside-down before laying eggs, but I don't think this is the
issue. Do you have any suggestions as to what the problem is and how I can
help my small friend?
<Almost certainly either water quality or water chemistry issues. Check
these and act accordingly. My prediction would be that if you [a] stopped
feeding for a few days and [b] did dechlorinated tap water changes to remove
all traces of the pH buffer, the aquarium would quickly settle down. Use
your test kits to check this.>
I'm also heading away again for a number of days and could bring a separate
small aquarium with me to monitor any progress but am wondering if it's best
to leave her be. Thank you for any insights.
<Hope this helps, Neale.>
