Tank Level Variation
using a book for guidance, I have determined that most of the small tropical, livebearing fish I am interested in generally swim in all levels of the tank, suggesting possible congestion and disharmony. I am wondering if my fears are exaggerated, ad if not, can be resolved by the pacemen of many plants, bogwood, and other such natural or artificial decora.
Would depend on what particular livebearers you are interested in. Many can co-exist. Many will also eat their young if they are not removed or provided with suitable hiding areas.Another important consideration in my view as well as others is, You will want to have two or three females to each male . In that way the female is not stressed from two or three males trying to breed with one female. Some livebearers can also crossbreed with others swords, platys and molly's for example, guppys and Endlers I have heard can also crossbreed. You may wish to set up a grow out tank maybe10gallons to place the young that you wish to keep or sell to mature in. That way they don't get eaten. Livebearers can make lots of babys so in my view some measure of control will be needed to prevent too many.Hope some of this helps. :)
thanks for the input. I was considering all the common ones, such as several molly varieties, guppies, swordtails, platys... Maybe a halfbeak, if I can find one. I was thinking of throwing in a small school of neon tetras as well, though their water pH range is not exactly intersecting with the rest... I've seen these species together in many photos. I was also considering a larger, herbivorous fish but the size in itself might prove dangerous. Some algae eaters would be thrown in as well. The tank would be 75 gallons, up from the current ten (this could be used as the breeding tank). How many fish could that hold, based on the species listed?
I may not be the best person to ask. When I think numbers of fish I also think Fish poop which= ammonia. Were it me I would prolly put no more than 30. I would also see that filter was able to move at LEAST twice the number of gallons the tank holds. Some will no doubt disagree but considering possible baby fish along with the others this is my humble opinion.
i havent been around in awhile, but it used to be a rule of thumb, no more than 1 inch of fish per gallon of water. all those livebearers will fool you cuz they are relatively small, so you think you can shove a ton in a tank that large, but in 1-2 months time, they will have multiplied severely. so i suggest starting off with perhaps 2 males, and 2-3 females per each male, so that puts you between 4-6 females that will probably start having fry within 2 months, if your water conditions allow.
i agree with the filtration comment, I recommend having a great filter, but make sure you take the neccessary precautions for raising fry, if that is the direction you choose to go. you will need some type of sponge to cover the end of the filter. what type of filtration are you considering? I recommend a rena filstar xp(3?) if you havent decided yet. 8) i have a 47 gal column tank and my filter keeps that baby going strong!
and if you don't already know, the parents of the fry WILL EAT the fry, so you will need some way to separate them until they are older. from my experience anyways... :shock:
as far as types of fish go, swordtails are my fav LB fish, and mollies and guppies are also fun. I am not familiar with halfbeaks, so I can't say. i believe neons would be fine with a group of livebearers, but I'm not sure about the bigger fish. I kept angels with my LB, and eventually all the smaller fish dissappeared! LOL
i wouldnt worry too much about where the fish swim in the tank, if you will be doing LB primarily. and lots of vegetation and good places to hide will be important for the fry if you don't use a breeding tank.
sorry for the novel...hope this helps! :oops:
How large do molly's grow? My handbook says 4in, but I can't imagine that. I'd also like to know what are signs of labor, or whether I have to guess the time of fry ejection.
The problem with keeping pairs instead of the suggested ratio of 2-3 females per male is that the male will constantly harass the female because he wants to breed all the time. Male livebearers have been known to harass females to death in this situation. Also, males of the same species (such as the male mollies) will view one another as competition, so having a higher male-to-female ratio can lead to violence amongst the males. Mollies will definitely reach four inches, as will swordtails. Platies and guppies stay smaller.
I see... would the larger mollies and swordtails pick on the smaller fish, especially the 1in neon tetra school?
This is my prospective lineup:
9 mollies (3 variations) 36in total
6 swordtails (2 variations) 24in total
3 guppies (1 variation) 3.75in total
7 neon tetra 7in total
1 generic algae eater 5in total
1 black widow tetra 2in total
77.75in total, a little over the 1in per gallon standard. I have a 10gal tank especially for fry, and connections to transfer them to once they have grown and crowded the tank. In the case of this tank, what kind of decors, plants, oxygen equipment, and filters would you recommend?
yes, i agree with batman. the male will most likely chase the female to death. you should get more than one female per male! spead the love! LOL anways...movin on...
the only thing about the fry separator that you showed me is that most of them are made of plastic, preventing normal water flow for the fry. this can be bad, as there will be so many fry that ammonia will build up and most likely kill them. if you can find a net one I would suggest using it if that's the route you want to go. or, you could set up your 10 gallon as you said, and use it as a fry tank. when your females look like they are getting close, move them into the fry tank until they have given birth, and then move them back to the main tank. that way the babies arent in harms way with the other fish. =)
also, you should realize that your LBs will most likely inbreed as well. molliesxswords etc.
i have sand as my substrate in my 47 gal tank, and i love it. very low maintenance for me. i use silk plants, which don't look quite as fake as fake plants, but you might consider a planted tank. =) i recommend a canister filter, as its in my personal experience that HOB havent worked as well for my needs. i love my rena filstar xp2, and i couldnt recommend it more! if you are planning to stock your tank to capacity, i recommend going with a larger filter than your tank needs. also, I prefer the natural look to the fantasy look. i like plants, rocks, driftwood, etc for decor. you might try researching what the natural habitat for mollies, guppies, swords, etc is.
and on a last note, I don't recommend stocking your tank to full capacity right from the get go. i suggest starting with a smaller group, and letting it grow in time. if you start off with all the fish your tank can handle, what will you do with all the fry? you mentioned keeping some, and it would put your tank way past what it needs to properly maintain water parameters.
just some food for thought. =)
Ouch, the Rena's pretty expensive. Not sure if it's a website glitch, but Petsmart is reading that all models, from xp1 to xp4, cost $190. I guess that's cheap compared to what's out there, though.
Yeah... I'll see what happens. Thanks for the input.
