Tank size: 10 gallons.
Testing kit used: API Master Freshwater Testing Kit
Water parameters have been the same for months and are as follows:
GH: 10(guess from the water company since I can't find testing solution for it)
KH: 80 The only thing I have to test out KH is strips, which are never accurate, but out of six of them they all say the same number.
The tank is about three years old, was re-done with sand substrate about two years ago, didn't change the filter or anything then, just the substrate and removed fish until things were settled. No further changes have been made since aside from new plants every so often.
The tank had one betta and four African Dwarf Frogs since the end of last November. So for about eight months. I did lose a betta recently to some type of tumor on his chin and got a new one who has been in there about a week. He's a young Dragon Scale Crowntail, I'd say about half grown, he's around two inches long. Three of my frogs were pretty small, one was fairly large. Two females and two males.
The betta was QT'd in a separate tank for two weeks. Yes I know it should be longer, but he was QT'd in someone else's home(another betta's five gallon tank that has been set up without issues for anyone for a year and a half). lol
I have about a dozen live plants. One Amazon Sword, an Anubias, two Umbrellas, a few stem plants, and one other that looks kinda like a leafy bush. I don't know the names of all my plants, sorry. I've had them all in there aside from the newest umbrella plants for two years now.
Substrate is sand.
Heater and filter are Aqueon brands that came with the tank when it was purchased.
Lighting schedule is about eight or nine hours per day, usually turn the lights on between 8-10am and shut them off around four or five PM.
The lights are ZooMed Ultra Sun 5500k bulbs.
Tank gets no sunlight except certain times of the year(usually dead of winter) it may get a little indirect light on one corner for about half an hour or so at the end of the day.
My water change schedule is every Sunday for this tank. I change out about 30% and vacuum just over a quarter of the substrate, different place each week.
Tap water is used.
Water conditioner used is Aqueon Water Conditioner with a drop of Seachem Prime since we had ammonia in our tap last year after a water issue when they came to fix the street pipes, yuck...just a bit of extra security since it almost totaled my other tank. lol
Foods are all frozen and Hikari brands that include: Brine Shrimp, Glassworms, Bloodworms once per week if that, tubefix worms, and beef heart once per week. They are all fed two bites of whichever food is given once per day, and are fasted once per week.
The abnormal signs: One died of seemingly nothing. I looked them over, saw no injury, bloat, swelling, marks, nothing up with the eyes, I didn't see anything wrong except they couldn't sink. I assumed it was swimbladder issues, petshop guy(as I call him, he's very good and isn't one of those who knows nothing about fish and gives stupid and fatal info to beginners, which I'm not, but he isn't as great with frogs unfortunately so options were few), also thought the same. He said I can risk it with peas or go with an antibacterial and hope for the best, I chose to do both and it cleared them up without me losing anyone else.
They would be unable to sink for about 24 hours and then would die. These issues have stopped. I had another frog in early November that died of the same, but I haven't had problems like that since then.
The issues I'm having now are: One died of what looked like air under the skin, she looked like a water balloon honestly, with a few air bubbles visible under the skin. It didn't look like bloat, it literally looked like she had air and water under her skin from nose to toes, complete body swelling, when she died I took a look at her, and that was my conclusion, though I have no idea what that was about. She floated about like that for two days and then passed away with no other odd markings, it was not shedding either.
Last night I lost another frog. This one had no floating problems. No bloat, no funny waterballoon-ness. His right back foot turned red. Kinda like your skin does when you get sunburned. And he had what looked like a little red spot on his side. It looked like it was under the skin, not on top. Other than that, I saw nothing on him. I thought I might have ammonia in the water, but none showed when I did a test. I have no idea what caused it.
I have only one frog left, my little male. =( He also shows no signs of anything, no red marks, no bloat, no swimming issues...I hope to keep it that way. T_T But it'd be nice if someone could tell me what's up, I have no idea and I love these little frogs. They're social creatures, so I doubt he's gonna like being alone for so long, but I'm not getting him any buddies until I figure this out!
I have not treated them for anything, I have no idea what's going on, it doesn't seem to be the same thing as last time. I put in a little stress zyme+ to help in case and repair any skin damage that may not be visible. I can't take them out and look them over, they're too delicate and I'm afraid to touch them, so please don't ask that of me. ^^; They're far too fragile.
