Why is that?




I knew there were consequences to be considered. :D

coz from what i read somewhere, it said that inbred fish exhibit many problems. Some times even making them more vulnerable to diseases also. And if i rem correctly it also said one place that the fertility goes down in each generation of in-breeding.

Don't know how true all of this is, but that's what i read.
Hope someone more experienced can clear things up :)
 
Your better of getting fish for breeding purposes from multiple sources to ensure a broad blood line. The viability of second or third generation sibling crosses tends to wain, making it difficult to get good quality fish. 95% of these crosses end in disaterous outcomes but the offset is you get 5% exceptional offspring. You need to be willing to use the rest as feeders. Don't take them to an LFS and make them somebodey else's problem...

most fish in petstores have been line bred. you probably have line bred fish in your tanks unless you have all wild caught or f1 fish.

maybe so, but that still doesn't mean that what i said was wrong.
And i feel it should be our duty as passionate hobbyist, that we should'nt introduce in-bred fish in trade.

i didn't say that you were wrong. there is only opinion about this, not right or wrong. line breeding created the discus' that we see today.
if both fish have some unique charachteristic that you are trying to develop, that is when you would do it.
if you just want to breed flowerhorns, then you should get a different mate that has some traits that you find desirable.
by the way, i do believe that inbreeding is why the EBJDs are so delicate until they reach 3 inches. if less people breed the blue gene jd back to the father, they will get stronger.
hybrids also end up with some fry with deformities. so does regular breeding. feed the deformed fry to other fish.
 
a side note on EBJD, I've noticed that the stock available is a lot harder than it was three years ago.

even the ones smaller than 3" have no problems.




Okay, so I think my fish are both male. I don't know if me adding the piece of slate pissed them off or what, but the big one stopped digging, lost the vibrant red chest color it had.

It is still chasing the smaller FH and the parrot, but not fighting the other nicer faded kamalau anymore.

Right now they are swimming peacefully together.

Both of them look like they have pointy breeding tubes, but they team up against the other fish.


Will the other fish in the tank stop them from breeding? Should I remove them? (2 small FH, 1 BP)
 
I don't know the sex of the BP, I've been trying to figure that out.
 
bps have large breeding tubes. it is fairly easy to sex them if you know what to look for. the female's tubes is rounded at the end or U shaped. the male's is pointier or V shaped
 
The problem is waiting for it to show it's breeding tube lol

The faders are giving the BP a hard time lately, so it's usually just hiding.


The largest kamalau got back it's color this morning, but neither of the two are showing breeding tubes anymore.

I've also noticed that the fins are getting longer on the fully faded kamalau.
