Care Guide:

Ancistrus sp. Rio Paraguay

Captive Bred - UK

Sub Adults 7-8cm+ (we have had a successful spawn from two we separated out from these so they are breeding size just not jumbo) 

We cannot 100% guarantee gender at this stage but it looks like we have 1 male 4 females 

Max Adult Size: 10 - 16cm (3.9 - 6”) these tend to get quite chunky and males very bushy noses. 
Temperature Range: 21 – 28 C
PH Range: 6.5 – 7.5
Does better in medium to soft water. 
Diet: Grazes on the biofilm and algae around the aquarium and will benefit from wood and other organic structures. They will however be quite happy to take a variety of prepared foods. As a treat, they enjoy green vegetables like courgette. 
We don't recommend feeding them large amounts of protein as their digestive system isn't really equipped to handle it and we often see bloating/"dropsy" issues. 
Habitat Ideally fast flowing, however they are hardy to lower oxygen levels and will only really struggle in very still aquariums.
Note: Bristlenoses have very spiky protusions behind their gill plates which they stick out when stressed/fighting. These will get stuck in a net very easily and hurt if they scratch or stab you. Be very cautious while handling.
