Therefore we need to protect and to separate them. Spawning boxes in the form of nets, containers, cones or caves are efficient solutions to ensure the survival of the fish offspring.

Advantage of spawning boxes: Protects fry from predators, safe breeding, easy installation, generous volume for better growth, ideal water flow

Easy to install: Slot the frame together, position in net, adapt holder to aquarium rim.

How do you clean the net of the spawning box?

Over time, the white net of the JBL NBox spawning box will discolour and become colonised by algae. You can simply place the net in JBL PROCLEAN POWER which can be 50% diluted if necessary. Within a few hours the net will be bright white again and only needs to be rinsed in clean water before being reinserted.

A great method if you want to breed and not lose your fry. You need a bigger tank to use this properly. Also separating sick fish in a short period you can use this.

malawi_aquaristic - German

Eignet sich perfekt für die Aufzucht von Jungfischen. Im Vergleich zu den herkömmlichen Aufzuchtkästen, welche nur an den Seiten kleine Öffnungen haben, kommt hier durchgehend frisches Wasser rein und sorgt so für ideales Wachstum der Jungtiere.

Zudem lässt sich das Netz ganz einfach unter dem Wasserhahn reinigen.

Dank der biegbaren Metallhalterungen kann man es super im Aquarium aufhängen, auch wenn es sich um ein Juwel Aquarium mit einer höheren Kunststoffumrandung handelt.

malawiaddiction - German

Super für die Trennung von Unterlegenden Tieren oder aggressiven Tieren im gleichen Becken, aber auch für Nachwuchs der noch zu klein ist im Hauptbecken zu schwimmen.
