What is special about the volume and dimensions of a 40 gallon breeder tank that makes it conducive for breeding?
Do you breed one pair per tank regardless of species? Once fry are capable you remove parents and raise fry in the breeding tank?It's more a tank for breeders to buy. It is an excellent size for raising fry. The name doesn't come from its usefulness for actually breeding fish.
It has a good volume, but isn't deep. Several might fit on a rack, especially as its front to back depth lends itself to stair type racks for easy access.
It's generally easy to get fish to breed, but the test of skill includes being able to raise them up as healthy individuals so they can be enjoyed by others. I'm sure there are hobbyists who are fish spawners, and leave it at that, but that label sounds bad.
Ignore the word breeder. What makes a good breeding tank depends on the fish. However the extra width has a lot of advantages.What is special about the volume and dimensions of a 40 gallon breeder tank that makes it conducive for breeding?
None of these three fishes are difficult to breed. If you want to actually raise frys they should be kept alone or optionally with some dithers that will not eat the frys. kribs and domestic a. cockatoo will easily breed in medium soft water (tds 100 is fine with lower kh value 3 or lower is good).The first three species I would like to consecutively breed are a. thomasi, a. cacatuoides and p. pulcher. The first two pairs are easy to net and transfer to the breeding tank but the pulchers are almost always hiding in rock caves and coconut caves within a 60 gallon. Even feeding time doesn’t usher in their appearance. Any suggestions? That’s problem #1. Problem #2 is I cannot differentiate male vs female a. thomasi. I know the dominant male. There is a smaller butterfly that may be the female. But I am not certain.
Well wild even if the common species are going to be more difficult in general. I use ro water for all my aquariums these days but 2 as i mostly keep dwarf cichild and pretty much just sa fishes ('cept loaches and rasbora which are asian).Thanks Gary for the information. I was set on Pelvicachromis kribensis Moliwe and waited three months to find them. I got impatient, a bad trait in this hobby, and bought wild pulchers from The Wet Spot. Two weeks later The Wet Spot finally had p. Krib Moliwe available. Bad me.
