My fishless cycle accidentally became a fish in!
I'm starting to think that my life with fish will never be dull. I'm cycling a 6 gallon bow front tank for my first Betta and it's about half way through the cycle. Today, I was looking closely at the tank to see how the plants were doing and thought I was dreaming when I saw a couple of teeny tiny transparent fish darting around! It finally hit me that the two small water sprite that I moved over from my other tank must have had some hitchhikers :shock:.
My other tank has Bloodfin Tetra and Zebra Danio, and I'm thinking the better possibility is the Danios because several of them have appeared to be pretty full of what I assumed were eggs. I've never seen fry yet in the bigger tank so I'm guessing the two schools of fish are taking care of any overcrowding issues before they occur.
I immediately did a 75% water change and took out the little piece of shrimp I was using for ammonia source. I tested the water yesterday and the levels were about .25 ammonia, .25 nitrite and only the amount of nitrate that is in my tap, I wasn't using much shrimp in such a small tank so the levels never really got too high so I suppose that's how they survived.
What the heck do I do for these little guys? I've only got flake food, dried bloodworms, and betta pellets here at the moment. So far I've only seen two of them, I don't know if any more will appear (there are a lot of hiding spaces in there). Fortunately for them, I've got a sponge filter in there, but otherwise, I'm kind of clueless here on how to keep them alive (and what to do with them if they survived, I'm already pushing overstocking in the other tank).
Any help will be appreciated!
Something similiar happened to me with tiger barbs. Not sure if tetras are the same but barbs hatch with a yolk sack (built in food supply) lasting a couple of days. After their food supply ran out I hatched baby brine shrimp. They also eat something called infunsios (forgive my spelling) tiny single celled organisms produced by decaying plant material. As they grow I took flake food and ground it into a fine powder. Or just put them back in the orginnal tank and let nature take it's coarse if you aren't prepared for dealing with the fry.
J dizzel has some good suggestions. One source for Infusoria is dried leaves like oak, beech, almond; some fish stores sell the latter. There are also commercial Infusoria preparations.
As tanks become established, and especially when there are lots of live plants including floating plants present, there will be a lot of microscopic food for fish. I have fry survive periodically and obviously they are doing so on this invisible (to me) food. Once they are at the size you can easily see them, the powdered flake food works well.
And you are correct in your thinking of fry not surviving in the main tank. Fish will, if happy and healthy, spawn regularly. But in the confines of an aquarium with so many fish (compared to nature), the eggs usually get eaten, or the fry if some should hatch, by any of the other fish including the parents. You obviously moved some eggs or more likely fry over with the floating plants. I once had Emperor Tetra appear in a tank where I had never kept this species, but they came with some plants I moved.
Well, I appreciate your concern for the fry; however, I'd do another water change and add the betta. Six gallons for a betta, live plants... you really don't have to go through that cycling tedium. Do your water changes and feed carefully and you shouldn't have to worry. As for the fry, grind flakes into a fine powder; however, I wouldn't plan on them being around very long. Don't mean to sound insensitive.
Thanks for the replies! I'm also seeing some little tiny white critters darting around the tank and on the tank walls but without a good magnifying glass I'll never be able to identify them more specifically with these eyes. I do not see them in my established tank so I'm going to go with best hope that they are one of the non-harmful creatures that my fish probably eat (they are about the size of a grain of salt or smaller and pretty fast). Will the fry eat those too? The fry are about 6 or 7 mm long, big enough to see but notbig enough for me to imagine them eating anything yet.
I do have 2 anubias, 2 wisteria, and 2 small floating water sprite in there, so maybe they will provide the invisible food?
edit to add: Fishmonger, I'm kind of with you there, I even mentioned to my hubby that maybe I should just get the Betta but now my son's seen them so that might be an issue even for a 14 year old "tough guy" LOL.
