Mudskipper (Periophthalmus sp.)
Mudskippers are amphibious gobies that spend much of their time out of the water on mud, roots and rocks, breathing through their skin and through water held in their gill chambers. This listing is a Periophthalmus mudskipper whose exact species is not identified, so the adult size and appearance can vary; most mudskippers in the trade grow to roughly 8–16 cm depending on the species.
What you receive
Each purchase supplies one fish in the size chosen in the selector.
Enclosure
| Setup | A brackish paludarium: most of the space as shallow water and gently sloping land (mud, sand, roots, rocks) |
| Water | Brackish, kept clean and warm |
| Cover | A tight lid with no gaps; mudskippers climb and jump |
| Humidity | Warm, humid air above the water |
Behaviour and diet
Mudskippers are territorial, and males in particular fight; give each fish its own area or keep one. Feed meaty foods: small crickets, worms, chopped prawn, bloodworm, mysis and brine shrimp.

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
