Full Care Guide
Discus Fish Care: Tank, Water & Group Guide
Discus are social Amazonian cichlids with specialised aquarium needs. OATA advises at least five fish, except an established breeding pair, and about 50 litres per adult—roughly 300 litres for six adults. Use that as a planning floor, then check usable dimensions, filtration, source water and the actual fish.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
