I am new to this forum and a newbie to the fish tank as well. Last night we lost a Dwarf Gourami as he was on the bottom breathing heavily and his tail was torn up (tail rot?) So I took him to Petsmart and they refunded the cost of the fish but also has water tested and the PH showed high as well was ammonia .5 if that sounds right and all they said was the ph was high. I bought the reducer product and will retest the water on Wednesday and see if more adjustment needs to be made. But in the mean time the other two Gouramis have very light sections of their tails looking like they are having problems as well and one of them seems to be always near the bottom of the tank. So I bought a 10 gallon tank and am running just an airstone in it and have adapted the two to it and am treating them with lifeguard. After doing this I now read that gouramis do not get along as they were all males. The two seem to be fine together though. When I get the water tested in two days I am going to get a test kit but I am color blind to a certain extent so reading a color comparison is not going to be easy but can be overcome. What is the likely hood that these two will get along? I have not seen any of them fight or bite each other and am hopeful they can coexist. The main tank (55)has to live plants in it I am just a a bit upset that we were sold three gouramis and nothing was said about them not being compatible. Feeling a bit overwhelmed as it seems everytime we turn around we are buying more and more stuff.
