Hey everyone... So I am having an issue with my 29 gallon tank. It has been set up for over 8 months now, and has quiet a few live plants in it: 3 Anubis, 6 Java Fern, 2 Amazon Sword, 1 Pennywort, 1 Moss Ball, and 1 Crypt. The tank is equipped with an AquaClear 50, temps on two thermometers read 77.7 and 78.7. Ammonia-0, Nitrate-5, Nitrite-0, Alkalinity-40-60, and pH-7.0-7.2. Maintenance is easy on this due to the all the plants, the size of the water changes is based on Nitrate levels, the level has never been above 10 in this tank. The changes are usually minimal, 25-35%. Beneficial bacteria is added after any fish are added, after water changes and bi-weekly to main the biofilter. I am having a problem with my Dwarf Neon Rainbows. I had a school of 5 and they were dying one by one over the last week. The last two I found this morning. I also lost a small angelfish previously to them dying. I am not sure what the cause is... I have two other angels doing beautifully, growing and eating like champs, 8 neon tetras also doing very splendidly. In addition to them, I have one Rosaline shark (I know he should have a school, but he was the only healthy one they had at the time, and he has a friend waiting on him to get get bigger to move to the 100gal.) 3 L/F Red Minor Tetra and two Redhead Eartheaters. The Eartheaters will also be moving to the 55 when they out grow the 29 and then to the 100 gal when they out grow the 55. there are 3 cory cats and about 8-10 ghost shrimp. I am not a novice at the hobby... still have some stuff to learn, but have had tanks for a few years now, and all of them doing well. Please help if anyone has any ideas... Also the Rainbows were the first to go into the tank.
