Handmade Bristlenose Catfish Breeding Log – Triangular Large

Give your Bristlenose Catfish a sheltered place to hide and breed with this Australian-made triangular clay breeding log.

Handcrafted from high-fired clay, this large aquarium breeding cave provides a secure space for Bristlenose Catfish and suitable cave-spawning L-number Plecos. Its triangular design creates a sheltered area where fish can establish a territory, rest or lay eggs.

The fired clay is aquarium-safe and will not normally alter your water parameters. Each log is individually handmade, so small differences in shape and finish are normal.

How to Use Your Breeding Log

Rinse the log with clean water before adding it to your aquarium. Do not use soap or cleaning chemicals.

Place it securely on the aquarium floor, away from unstable rocks or decorations. Position the entrance so your catfish can enter and leave easily.

For breeding, choose a cave that gives the male enough room to enter, turn and guard the eggs. Many cave-spawning catfish prefer a snug fit rather than an oversized space.

If keeping several territorial catfish, provide enough suitable hiding places to help reduce competition.

Complete Your Catfish Setup

A breeding cave is only one part of a healthy aquarium. Your fish also need clean water, suitable food and stable water conditions.

Frequently Asked Questions

Will this breeding log help Bristlenose Catfish breed?

It provides a suitable sheltered spawning site. However, successful breeding also depends on healthy adult fish, suitable water conditions and proper feeding.

Can L-number Plecos use this cave?

Yes, some cave-spawning L-number Plecos can use triangular clay breeding logs. Check the opening size and length against the requirements of your particular species.

Will the clay affect my aquarium's pH?

The high-fired clay is designed to be inert in freshwater aquariums. It should not normally affect pH or water hardness.

Can I use this log even if I am not breeding fish?

Yes. It also provides a sheltered resting area for compatible catfish and other suitable bottom-dwelling fish.

Are all the breeding logs identical?

No. Each log is handmade in Australia. Small variations in dimensions, colour and shape are normal.
