There is nothing new with this type of spawning frame but it is very easy to make and very cheap!
I bought the terracotta tiles from tilemart in Mitcham Melbourne for $7.80 for 20 tiles. 6 of these frames work out at $1.30 each not including the silicon.
I have used selley's glass silicon as it is aquarium safe and will be strong enough to hold the tiles together. I already had this tube of silicon but costs around $7- which would be enough to make 100+ of these spawning frames!
Assembly was very easy (see pics below) i smoothed out the silicon with my finger tip. It took less than 10 minutes to make all 6!
Anyhow just a cheap very functional idea for those that want to breed their loved ones!
Cheers
