Hi, does anyone know if one pair of kribs would be okay in my 10 gallon tank? It currently has 5 platy's one pleco and a goldfish which i think I'll be taking out for them.:huh:
Kribs in a 10 gallon

No, definitely not. One krib might do okay in there, but 2 would need at least 20g. IMHO, a pair of kribs should really have at least 25g all to themselves and breeding kribs should never be kept with other fish unless it is a very large tank. I tried keeping breeding pairs in a 75g community, and they killed several of my diamond tetras and kept all the other fish in hiding and stressed. Even when I took out one of the pairs and only had 1 breeding pair with a few unmated females, they still kept the tank stressed and killed another couple diamond tetras. They are awesome parents after the first 1-2 batches when they finally get how to care for the fry and don't eat them, but they will very aggressively protect their young.
Also, the pleco should definitely not be in a 10g. I'm guessing it's a common pleco, which get over 18 inches and need at least 125g! Goldfish also need bigger tanks, and they need colder water. Goldfish should never be kept with tropical fish like plecos and kribs. Goldfish need at least 40 gallons for the fancy kind (fantails and such with the rounded bodies and slow moving) while the regular ones with streamlined bodies need at least 55g each.

Fancy goldies do just fine with temperature bracket of 74-76 degrees Fahrenheit. Actually, they prefer their water warmer than the pond types require. With fancies, I aim for 10-15g per fish. For pond types, I aim for 20g per fish. That does not mean a 20g or smaller is okay. A 30g itself can house two adult fancy goldfish whereas pond types do better in larger tanks in which case a 75g would be more efficient with better floorspace than a 55g although you have to realize with smaller tanks, maintenance becomes more tedious. I quarantine new goldies in my 10-15g tanks and the maintenance is more frequent than would be necessary.
IHMO, fancies really need more than 15g each. Many can get up to 8" or more, and I just don't see how they could be happy in a 15g tank. Even so, they need pretty good filtration, especially if you did go smaller than 30g.
It's true that fancies can do well in water that is a little warmer than which is normally recommended for pond types, but I still would not mix goldies with tropicals. IMHO, goldies should only be mixed with other similar-sized and similar-shaped goldies.

Bazil, if you read my post, I never said a 15g by itself is feasible. I already clarified that in my previous post. I was referring to large tanks and calculating as a guideline how many goldfish may fit in a particular tank rather than a small tank by itself which is not feasible. And where in my post did I say to mix them with tropicals? There are very few plecos that can conform with goldfish just fine as long as they do not act aggressively. Most plecos can handle temperature that goldfish do without them trying to suck the slime coat of the goldies.
Two fancies in a 30 gallon tank, with 2-3X filtration and daily water changes, is in my opinion, adequate. Since goldfish are schooling fish to a degree, and require at least one other goldfish companion, the situation of a single fancy goldfish in a 15 gallon should not arise.

Its not necessarily a divorce ... female kribs need their space when tending the fry. Males are supposed to be a foot or more away keeping other fish away. A 10 gallon tank doesnt give much more for the male to keep his distance. I am guessing you wouldnt notice this same behavior in say a 3 tank. Kribs arent the only ones that act this way, Nannacara
My buddy Bill breeds his in a 10gallon. I am getting some fry from him but i was planning on breeding in a 29g. just to be safe, ya know?
Sorry Lupin. I was just reading too fast and missed where you said that it doesn't mean that a 20g or smaller would work. Human error on my part. As for the mixing with tropicals, I was simply clarifying for the original poster that even though fancies can be in warmer waters, it's still not a good idea to mix most types of tropical fish with goldfish due to behavior, etc., and that many tropicals still need slightly higher temps. I didn't really explain that very well in my other post. Again, I'm sorry.
