I came home from work today only to realize one of my young Honey Sunset Gouramis was dead. There are 11 other fish, one other gourami, in the tank. This fish was fine, my tank is fine, I have checked everything out. I am not sure what has caused this to happen. The fish was only about half grown. All the other fish seem to be acting normal, I am going to be on the look out. Was wondering if there is anything special I should do.

Hi Mgreen! It is always hard to loose a fish. Can you tell us how long this tank has been set up? How big is it?
Do you test your water? and what are the readings? Any live plants?
Temp and PH too if you can. This will help us to maybe sort it out for you.
Sorry for your loss.

Thank you, Tank is six weeks new, temp is 76. Ihave a ph and amonia tester intalled. Ph is high, have been having trouble keeping it down it is currently 7.8. Ammonia is at a safe level. There are no live plants. 36 gallon tank with 4 tetra, 4 glofish, 1 otocinclus, 1 algea eater, and now only 1 gourami. Did the routine 25% water change 2 weeks ago.

ok so a couple of things that comes immediately to minds is you may not be quite thru the cycle. it can take 6-8 weeks in total, without live plants.
Also you mentioned trying to lower your ph. this is not a good idea at all. it is very stressful on fish. How are you trying to lower it and why are you trying to lower it?
You should be at either the end of the NitrIte stage or entering the NitrAte stage. Can you get a API liquied testing kit at some point and post your numbers?

I have not done anything inparticular to lower the Ph number, just water changes. I was however, under the impression that ph should be at 7, which is why I wanted it to lower. I have to get a test kit from the store, but this may take a few days because of my schedule, however if I have any further problems I will make it a must to save face with my new tank.

Well 7 is Neutral but some fish, depending on the species like high or low ph. If you have live bearers like mollies, swordtails, guppies, then the ph needs to be toward 8. If you are into Discus then you need softer water at 6.
So it depends on the fish you wish to keep, and it's needs.
Mine is 8.2 and I have a huge abundance of babies.... mollies and swordtails.

I see, I have tetra, glofish, and Gourami. So these are hardy fish..which would mean high ph is good?

High PH isn't necessarily good for those fish.. but changing it is probably going to cause more damage. What exactly is your ammonia? The only safe amount is 0. What is the other species of gourami? They dont tend to get along well usually. Oh.. and what is the algae eater?

Ammonia is zero, I have the in tank tester. The other Gourami is same species, Honey Sunset. Very docile, both of them were. THere are two algea eaters, one otocinclus and the other is a basic algea eater.

one thing i notice, you say you did a water change 2 weeks ago? they should be weekly, if not more frequent.

also, how long had this particular fish been in the tank and when was the most recent thing added?

these can both help determine a reason.

Every week? I was told monthly 25% water changes were normal. These fish were added about a month ago, most recent add was two weeks ago with the water change I added an algea eater.

What exactly is a basic algae eater? Common Pleco ? Or does it look somewhat similar to your Oto and is maybe a Chinese algae eater? Either of these need to go. A Bushynose Pleco would be good, although since you already have an oto I would add more of them instead, but you need to build up a supply of algae for them first.

Chinese Algea Eater. Was told at a local store it was an oto, however being a new aquariust I was tricked. Was thinking of returning this fish. Tank is fine today, still very unsure what led to the death of the Gourami.

return it. chinese algae eaters end up being problems. get another oto or so if you can.

I would return the Chinese Algae Eater (CAE) as it unlikely in a tank so young that it will have enough algae yet to keep it happy. They can also be aggressive and need a 50g+ tank really.

A lot of aggression in aquariums goes unnoticed, so it is not without possibility that the CAE caused the death of the gourami.

This was my thought, he is very fast so I was waiting until a water change, when all decor is out and water is low to help myself. What I want is another oto, 36 gallon tank should easily sustain two otos.

Yes and no. Most of the time Oto's need a supply of algae in the tank or they will starve themselves. Once they get settled in and feel comfortable they will accept other foods after that. Get rid of the CAE and just leave the one oto in the tank for now and see if he survives. If he does and you get some nice algae growth I would suggest adding 3-4 more at that point, since oto's are schooling fish.

Once you eventually add a couple more Oto's you will see them more. They will be more comfortable to come out just knowing they have "others" in the tank with them.

i have to go back to the water change thing. once a month is not nearly often enough. most people on here do minimum of 20% a week. a lot do closer to 50% a week. a month is too much time for stuff to build up in the water, not anything you can see or test for, but stuff that is very stressful for your fish.

i have to admit, over the holidays i went almost a month without a change. i paid for it. i had one fish get ich (she and another one later died, but i'm not sure that it was related). ich happens when water condition gets too bad for the fish and they are stressed from it.
