i think my fish might actually only be about 8months old actually.
I feel quite bad as ive only had the tank about 2 months, and at first i overstocked it by accident but then the betta ate 7 of the neons in 2nights
putting me back to where i am now with a good amount of fish.
3 brislenoses
1 zebra danio
3 neon tetras and the betta.
ive not lost a fish due to the water quality, but I didnt do a water change for the first 4weeks as i thought you were ment to leave it to cycle
anyway in that time i had tried to get plants to live in with no success so the water turned a bit smelly so i got some stuff that took the white cloudy water and made it clear and that worked. but now is only the first time ive cleaned the gravel (ive obviously netted out uneaten food and given it a bit of a clean but not a full clean)
i also changed the filter block thing the other day
which i think was a bad idea as someone said ive probobly restarted the cycle 
anyway all beginners mistakes and learnt from.
but its my fault he's in this way now
just hope ive caught it early enough.
ps 2 of the neon tetra had a few white spots on them the other day (now they only seem to have 1 on them each)... i might go and buy some ich stuff after just reading about it but after the vigerous water change i did today i might just keep an eye on them instead.
and the 3 bristlenose guys are doing awesome and theyve grown pretty fast now there about an inch big and pretty fat
ps
its more like a totally washed out colour / maybe slightly fluffy ( i read a treatment for something called velvet in the shop but i dont think its this, maybe )
nothing stringy (other than today after adding the melafix and the airstone there seems to be a couple of stringly bits with bubbles attatched to him but i assumed that was just the infection clearing a bit.
