You guys never seem to answer the real question. Same solution every time: You are overcrowding, bla bla bla... The tank is not going downhill. Its been up for more than 3 years with the same fish running on a wet/dry, uv
, and a protein skimmer.
Like I have said in another thread, I have seen many people that have more advanced and more marine fish than me with the same size tank and have been raising it longer than me.
Steve, a niger won't get to that size in a 55gal aquarium no matter how long it lives.
You guys are quite predictable. Please read more books on aquariums and find more solutions to problems other than overcrowding.
This will be the last time Ill be at this useless forum.
