15 Gallon Stocking Issue

Hi guys!

While I was at Petsmart today, I picked up a couple guppies and ended up being given what appears to be a young Glowlight Tetra who was randomly hanging out in the female guppy tank. The lady at the store actually seemed to know what she was talking about when I was just talking fish in general with her, but she said that a young glowlight tetra will join a group of guppies if raised with them from a young age. Is this true? If not, I'm upgrading (darn MTS!) to a 15g; Aqadvisor claims I should be able to house my guppies with a small shoal of glowlights with the filter I currently have.

What are you guy's feelings on this set-up?

Thanks!
Leah

i think that tetras will be far happier with other tetras. I don't really know that guppies shoal with each other either- the little tetra will probably be really stressed. if you can, upgrade to the 15, and get him some buddies :)

That's kinda what I was thinking too. I got the 15g today, so it'll take a day or two to get things in order, but it'll get done. I'd like to have at least a day or two to get the filters running and for a bit of bacteria to establish itself in the new substrate. Then maybe I'll move the tetra in first and leave him there for a couple days after that to give the tank a tiny amout of bioload.

15 Gallon Stocking Issue

Hi everybody,

Today, I took the plunge and got a 15 gallon tank to upgrade my 10 gallon (I was thrilled - it was on clearance at Petco for $35 and came with a hood, light, heater, and filter). While there, I also somehow ended up with a free juvenile Glowlight Tetra who was, for some odd reason, in a female guppy tank. The lady there said that a glowlight that's raised with guppies will shoal with them, but the consensis in another thread was that the little guy would be more happy with a shoal of his own kind.

So the delema I have is if I can comfortably house a small shoal of glowlights with my seven guppies in the new 15 gallon. If not, I can keep the old 10 gallon going and split them up. I'd do that anyway except that I live in a dorm and moving the two larger tanks and my betta home for breaks may get a tad interesting (not to mention that the dorm has a rule that any number of fish tanks in a room can't exceed a total of 30 gallons - I'd be at 30.5 :P )\

Gosh darn that multiple tank syndrome!

Thanks for any help/advice!
Leah

In my opinion you could definitely have a school of 5 glowlight tetras and 7 guppies in your 15 gallon (with room for a few more of either.) Just keep in mind that if you have female guppies you will have a fair amount of fry in a bit. this will take up more space. so if you do have females I would suggest getting fewer tetras so you have extra room (or be prepared to spread the guppies to your other tanks :)

With fish as small as these you could follow the 1 inch per gallon rule. (i've heard that for guppies you can have about 2 guppies per gallon. this would just require more frequent and larger water changes.)
Hope this helps!

Thanks! To the best of my knowledge, all the guppies are male and have done pretty well together because there've been a lot of sight breaks with the plants. However, I'm not sure with the younger ones as I'm not very adept at sexing them yet. If I do have a female, she may have to go to a different tank or something if only for her sanity - one female and six males would be a nightmare!

:) Typically males should be fine together (especially in larger groups like what you have.) Typically petco seems to do a pretty good job sexing guppies. The males tend to have bigger more colorful tails. Also most females do not have much if any color on their actual body.

I would either return the glowlight, or acquire another 5 or 6 to make a shoal of 6-7. This fish is a characin, and characins are shoaling fish, meaning they live in large groups. They must be kept in a group, and 6 is considered the least number though more is always better. There are reasons for this.

Shoaling fish evolved that way for various reasons, and when they are denied a group it can be very stressful. This weakens the fish, but it can also increase aggressive behaviours. Even normally peaceful fish like glowlight tetra can get nasty when they are alone, or in a small group of 2, 3 or 4. And characins have teeth, lots of them, and aggressive behaviour due to stress is likely to show up as nipping other fish out of frustration. And the flowing fins of male guppies will be a real target.

We have fish profiles, second tab from the left in the blue bar across the top of the page, and each profile contains info on numbers, etc. You can click the shaded name in posts to see that profile.

Edit: I came across the same issue in another thread so I merged that thread into this one. It is best to keep a topic to one thread for consistency. B.

Thanks Byron! Sorry about the thread mix-up. Would it be feasable to keep 6+ glowlights in the 15 gallon with my seven guppies if I have an Aquaclear 30 and the tank is fully planted?

In all honesty, I took the glowlight figuring that I'd have to get more of them so they could shoal. I do really like the little bugger - he's got bunches of personality and is pretty darn cute. If I can't fit them with the guppies, should I keep the guppies in the ten gallon and have a larger shoal of glowlights?

When I was planning on upgrading, I had thought to keep a single species of cory in the new tank. I'm guessing that that'd be pushing it now that the glowlights have come into the picture?

I think you should have enough space to have a shoal of glowlight tetras with your guppies. especially if it is planted, has a filter rated higher than the tank requires, and you just take good care of the fish overall. If it's make you feel better you could definitely have the guppies in the 10 gallon, glowlights in the 15 gallon, and probably have room for a small shoal of cories.
