I've had a 65 litre tank for over a year, inhabited by 2 'tiger fish' (I'm sorry I don't know the proper name for them) about 5cm long.
With these were 14 tetra neon (each about 1.5 to 2.5 cm long)
There have been no problems - regular cleaning etc and all fish were looking healthy and happy for over a year.
One week ago I added 3 Ancistrus (about 2cm long, black with very small white spotting all over body) in an attempt to keep algae from building up in order to keep the tank looking better between cleanings.
The last week, feeding routine has been the same as always.
Today I return from work and find all neon and ancistrus dead (((((( - some of them had a whiteish mildew-looking covering on part or all over.
I've googled compatibility charts etc but find no direct advice that there was some issue.
What have I done wrong as this is very upsetting for me (
