Cichlids: Types, Care & Tank Planning
Cichlids are a family of roughly 1,800 accepted species, not one care type. Before buying, identify the exact species and source, then compare adult measurement, usable tank dimensions, social system, territory, tested water, diet and an exit plan. No family-wide minimum tank, water range or tank-mate list is safe.

Port Acara Brown Cichlid (Cichlasoma portalegrense)
Port Acara Brown Cichlid is a hardy New World cichlid with quieter colour, strong pair behaviour and a useful tolerance of slightly cooler tropical conditions.
Quick facts
- Scientific name: Cichlasoma portalegrense
- Adult size: about 15 cm
- Minimum aquarium: 200 litres or larger
- Temperature: 20-26C
- pH: 6.0-7.5
- Diet: omnivore
Care and setup
Use a mature aquarium with sand or fine gravel, roots, rocks, open swimming room and broken sight lines. It is more manageable than many large Central American cichlids, but breeding pairs still defend territory.
Compatibility
Choose calm robust companions that will not crowd a pair: larger tetras, peaceful catfish and similarly sized cichlids only where space allows. Avoid tiny fish, fin nippers and cramped mixed-cichlid tanks.

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
