Hey all, brand new here to the forums with a quick question about what I think was a death by fungus. Been working on getting my newly setup tank cycled O-naturale and it cost me a betta. I added a betta and a dwarf guorami 2 days ago to start my cycle after having the filter up and running for about a week by itself. This morning both the fish were seemingly OK swimming around at their leisurley pace. They were not terribly fond of one another, but I never saw them doing any fin nipping, just a lot of strutting around. Anyways, came back to the tank this evening 12 hours later and the betta was dead amongst some of my plastic plants with a nice white fuzz around his fins and gills. Sounds like textbook fungus to me.

My question is, how much is my Gourami in danger? I did a 2 gal water change with a little seasalt as I've read lots of reccomendations of a saltbath for fish. Hes the only fish left in there with no sign of disease so I'm crossing my fingers, but I'd appreciate your thoughts.

Some tank stats: 20gallon in a more cuboidal shape rather than the standard 20 long. I've got an eheim hang over filter, airstone, pretty standard boring gravel, overhead lights with a lid, some plastic plants, and a pirate shipwreck :p. Chemistry has yet been unchanged since I added fish... pH 7.8 (thank you lake erie...), NH4/3 4.0ppm, Nitrite 0, Nitrate 0, temperature 75F. obviously the tank hasnt even passed its first cycle yet, so I've got a way to go.

I'm just hoping that I dont wake up tommorry and find my poor Gourami dead like the Betta. Should I pre-empt with fungal meds, or adopt a wait and see approach?

Your thoughts are much appreciated.

Mike
 
A little Update:

Woke up this morning and the Gourami appears normal. Hes still swimmin amongst my fake plants and puffs himself up when I come near the tank. Hopefully he'll still be like that when I get home from work...
 
The first thing you did wrong was put a gourmai with a betta because a goruami will not nip or fight it but it will harrass the betta to death.

My LFS warned me this might happen being both of the family of Anabantidae, but I guess their caution wasnt strong enough for me to use some of my own :whistle:. In watching them I never saw them nip at each other, and they kept to their own sides of the tank (Gourami on the left Betta on the right). When they did get close to one another they'd puff themselves up and flare their fins and contrary to the assumption, it was always the Gourami that backed down... Albiet very slowly, but he backed away first. I never observed any chasing or quick harrassment.

I guess I was more surprised at the speed with which the Betta contracted and perished to the Columnaris (thanks Wilder). I've never had a "hardier" fish contract and perish to a disease in less than 12 hours :dunno:.

I'm gonna operate on the assumption that since the Gourami still hasn't contracted the bacteria that he'll be ok. If any of you think otherwise let me know. Thanks for the replies thusfar, I appreciate the input

I think the biggest issue is that your ammonia is at a level that's not compatible with fish life. Even fish with labyrinth organs can be adversely affected by toxic ammonia levels. I would wager that this may have made the betta more prone to disease. Also, you never quite know when fish might "turn bad". Even though the gourami backed down initially, particularly with a sick betta, the tables could have turned rapidly...

I'd recommend doing daily testing and trying to shoot for an ammonia level less than 1.0. It'll slow the cycle down, but it'll be easier on the fish. You might consider a fishless cycle too. HTH and good luck~
