Hi So I have a dirted, heavily planted 28 or so gallon tank, lots of wood so a bit of tannins. Tank is about 14 months old. Mostly scarlet badis, which breed fairly frequently, and some exclamation point rasboras and recently 11 green rasboras (sundadanios). Duckweed, Anubias, Hygrophylla, java moss and more.

I had 5 bumble bee gobies that I removed, who I suspected were tail nipping badis, and causing some mortality.

More recently, Ive suddenly had a die off of the green rasboras- originally had 11 (wild caught), they had maybe a 50% attrition at the LFS, but mine were really robust and got very sturdy and did well. Suddenly I noticed a few less, then yesterday one going semi upside down, and today a different one dead, and another doing the bad equilibrium thing... 3 noted for sure in 2 days...

Additionally I sometimes have badis suddenly lose color and seem bloated and then dont last long, but the majority seem the absolute picture of health. Tank is not overstocked, I usually preform a 5 gal change about once a week but have gone longer without issues except an increase in tannin. Yesterdays change was the first I used excel and not dechlor.

Water is fairly hard which apparently the rasboras dont prefer, but they were doing really well in it. I dont have too many water test analytic to share. Fluvial 207 and aerator, fluvial plant 3.0 light. I feed them black worms which I raise and feed organic broccoli etc, live or fresh refrigerated baby brine, frozen daphnia, and for those who eat it, micro pellets.

I do have a dirted tank with organic potting soil originally under the gravel, which has now migrated up somewhat due to the snail activity. I do get bubbles occasionally which indicates some gas, and when I poke it I always get some burps.

attached is a pic of the tank and the little male badis who has suddenly taken a turn, keeps his mouth open, bloated, and has a scale or other protrusion on his head won't eat. thanks in advance :(

Any hint of a bad odor, like sulfurous smell or does the tank smell like regular fish water?

I would say testing is really the only way to know what's going on with the water... My suspicion is that you may have more than one issue.

My questions -

1 . Were the rasboras quarantined?

2. How much and what size gas bubbles are you getting from your substrate?


I personally would separate the fish from that tank, quarantine them hold and treat them with some gram A and gram B antibiotics and some prazipro...


Just follow normal QT routine and best practices... Also stop feeding them until you get this set up!

Then work on testing and treating the tank for any possible rogue anaerobes in the bottom of the substrate, you can use a syringe with Excel and inject into the bottom, or
some other method... Treat the main tank kinda like the QT tank and then recycle the BB with some new BB supplement after you change out the water a few times...

The only thing you know for sure right now is that you will probably lose more fish if nothing changes or if you can't narrow down the cause...

Also test your tap water... I had just recently found 8ppm Nitrite in my tap and was making some fish sick on WC even with prime...
Summer can cause issues with tap water quality in some parts of the country.

Just what I would do.. I've never had a dirted tank though with wild caught fish. I hope some of this helps 😬

Thanks for the reply-

Unfortunately I dont have a great quarantine setup and they usually pass before very long...

The rasboras were quarantined at the LFS, stressed and wild caught (I dont like the wc thing much, the LFS got a second batch and they all died.) They definitely had ich and I jumped the gun and bought them with a tad still showing, but it cleared up. But like I said, they settled very well, got much bigger, then this..

Bubbles look like a few bubbles coming up.. video wouldn't attach so here's a screenshot

. they do it when I poke, and also occasionally just come up, rarely though.

I was reading a bit about anoxic soils and gasses and it seems a minor worry from a brief perusal.

I dont have a great sense of smell so havent detected sulphur, but ill try to get someone in who does. Its just so odd for fish to generally be so healthy then turn suddenly. One could chalk it up to small fish=fragile, or lack of daphnia and getting impacted from soft food. The badis dont really like frozen daphnia and live is hard for me to find. I do occasionally get sort of "scratch" looking whitish marks on some that is way less vivid than the bright spots of ich.

Get a sponge filter and a stronger air pump

Very basic question, what's your Amonia, Nitrite and Nitrate levels?
hi Vaonstav, zero. IM at a loss. the only thing I can think of is:
-possibly a piece of wood I have thats leaching something, most are manzanita, some are found driftwood I boiled for a long time previously.
-possibly a rock I placed that is leaching.. my water tests very hard but thats normal here..
-Possibly too deep soil/ toxic gasses are dissolved in the water. Doesn't seem too likely from what Ive read but most of my plants are not really rooted in the substrate, though some hygrophila and a few others are.
-Possibly Ive introduced a bacteria or parasite from feeding live mosquito larvae and daphnia... Local fish person doesn't seem to think so. The fish get some raised whitish spots where scales lift and lose color before bloating and dying, but many seem unaffected. Losing too many though!
-Possibly something with my blackwoms- I feed them organic boiled broccoli etc, and keep them in a aquarium separately...
my shrimp, snails, and loaches are all fine. Just badis and rasboras seem to have die off, mostly badis I have now lost all my females tragically. Plants all thriving.
