Let us know how the fish are in 6 months time pal ?Hi....thank you very much for your message is very interesting...is my very first aquarium with first setup in November and i got many things to learn and to know...i always listen everyone first but then i take my own decisions and the answer from Mr Colin above is the one i was needed...going back to you tetras they was 6 and two of them they had tetra disease so FOR NOW only 4...same for dwarf chain loaches they was 6 but 2 of them the very next day i bought them i found them one in the filter sponge and another one the following day in the middle of a plant...the tank has been set up with 3 different substrates...thats right 3 you reading well...soil, gravel and fine sand...funny enough Coridoras they love soil section...and as soon the problem which I am having in my tank which is actually the main reason of my post and with no offence was even more appreciated than the informations you gave which i do already know...you forgot to say that if Borneo suckers are changing colour is because the water is too hot!!! Slowly slowly i will do some adjustments to your "schools" however i think fishes are like people...they got their own character and you will be surprised when you will see a fighting fish being chased in a very friendly way from a dwarf chain loach or when the male fighting fish is playing all day long with the output of the filter water swimming against the current and then turning quickly and enjoying the way back like a children slide without even considering the presence of 3 beautiful pretty girls from the same species which they play with guppies...and going back to you to keep these fishes as they deserve to be kept there is only one way...the wild...many thanks Master
