The "dump tank" community tank

[Magnum Man]

So, as I start looking at breeding fish, to me it seems evident that anyone who selectively breeds, must have a "dump tank", that culls get put into, and maybe more than one tank, depending on water types and fish compatibility... I see these tanks as selling / giving to the local pet store, when they start getting full... maybe keeping back any fish that I find too interesting, to let go, but occasionally emptying those tanks... how do you guys handle this situation???

I'm slowly starting to acquire some ( Poecilia velifera ) Sail Fin Molly's,
wow... isn't he pretty...


these will only be available as "assorted" my interest is in as "wild type", looking as possible ( green, and maybe some gold, but the dalmatian look will not be bred in this house, as well as non sail fin throw backs ) so I'm going to donate a 65 gallon tank as a dump tank... these tanks won't be in my main group, and will be visible to any visitors, so sparse accommodations, to easily purge, when the tank starts getting full... I'm actually thinking about a couple terrestrial plants with the main being those currently unused realistic plastic plants that got mentioned in that thread, that I can just grab out before a pet shop purge...

anyone want to talk about their cull fish???

I'm not breeding anything other than incidental CPDs but in the past my culls became tasty live foods for bigger critters.

as do my shrimp... the Molly's I listed can get 5-6 inches long... I'm sure my bichir would eat them, and I would hope I could tell keepers well before they are full sized... but assorted sail fin Molly's would probably be accepted at the pet store

I have been breeding j. transcriptus Gombe and a. cacatuoides. My yellow tiger endlers and red coral dwarf Platy breed without my intervention. I have not had to cull any livebearers. Between local fish stores, and an online rehoming site, there is never ending demand for colorful, live bearers. So far I haven’t had to cull any Julies. I have given around 15 away and sold around twenty. However I have culled 6 Cockatoo, which are runts that no one wants. I have them in a spare tank. My plan is to aggressively feed them several times a day for the next month. If they are still stunted and lack color, I will regrettably euthanize them. Definitely the worst part of the Hobby.

I don't think I would "euthanize" my culls, I may use some as feeders... while not truly line breeding, I would be trying in a way, breeding back to wild look, without lots of odd balls coming out with future generations , and breeding for large size, and big sails ( been done many times in other places already )

culls would just be fish I didn't want breeding
