1. Concern #1: Breeding traps like these make mother fish nervous, they swim in a frantic fashion and try desperately to get out, this increases stress and may even kill the mother. This is a true statement, so it is important to make the mother as calm as possible. This can be achieved by dimming the lights in the aquarium (I turn the aquarium lights off for as long as 2 weeks, until babies are born), feeding the mother some very good food like freeze dried bloodworms, and by not disturbing the mother in general. Fish are instinctively afraid of moving shadows and vibrations, so try to not stick your face against the aquarium glass too often. In my experience the mothers become very calm after 2 or 3 days. My advice is to place the mother into this trap late at night just a few minutes before you shut off all lights in the room. The green coloration of this trap was intelligently designed to reduce stress, making mother fish feel like they are surrounded by plants.
2. Concern #2: The breeding trap is too small and will stress large livebearers like swordtails. This is a legitimate concern, but I have now used this successfully on large 3-inch swordtails (excluding tail length, or 6-inch swordtail if I include the tail length). The siphon mechanism of this trap increases the circulation of oxygenated water into the trap, so poor oxygenation should never been a concern as long as the aquarium has proper oxygenation. Experienced fish keepers know that pregnant livebearers that are close to birthing will swim very little and either stay almost motionless close to the surface or near the bottom of the tank. For this reason the small trap size in and of itself adds very little stress. Livebearers including swordtails, platies, mollies, and guppies give birth every 28 to 35 days. My advice is to trap the mother just a day or two before the 28th day, to minimize stress.
3. Concern #3: Breeding traps are not necessary and a densely planted tank is adequate. This statement is true for many live bearers like guppies, endlers, platies, and most mollies, but it does not apply to some domesticated species like albino lyretail swordtails. Even with a densely planted 10 gallon tank containing 80% plant by volume (java moss, cabomba), swordtails will deliberately seek out and annihilate its fry. Selective breeding for coloration over several decades has inadvertently introduced this negative behavioral trait. If you are finding less than 40 swordtail fry per mother every 30 days, then your breeding tank then you are losing fry.
4. Concern #4: The fry trap is collecting the mother's feces. This is true and is a good thing. It makes it so much easier to clean the trap. Just throw our the collected dirt. No need to siphon anything.
5. Concern #5: The fry are not getting siphoned into the collecting trap. I disagree with this statement. In my experience using 4 of these traps for the past 3 months, I am collecting 95 to 100% of the fry. Check your airflow to make sure that there is sufficient water flow into the trap.
6. Concern #6: There are other less expensive traps that do not require an air pump. That is true, but those traps reduce oxygenation to the mother and the holes in those traps are large enough that reviewers have commented that the babies sometimes escape into the main tank or their tails stick out of the holes such that they get eaten by fish in the main tank. That has been my experience as well, and I've tried ALL the other models sold here in Amazon.
cons - only works properly when attached to air hose
comes a little plastic piece that acts as a spacer between the incubator and the fish tank wall. if you dont put that piece in, the fry will all escape through that hole. in addition, if you dont attach a hose or a plug to the hole that the air hose is meant to be attached to, the fry will escape through that too.
at the top of the green V-shaped piece there is a little ledge and some fry manage to land and stay on that ledge... until the mom eats them, they should redo this w/o that ledge.
