    That is a fun question! For rabbit snails yes, they are dioecious, meaning there are males and females. But other snails are hermaphrodites meaning they are both male and female. Here is a fun video on snail sex:

    Like a lot of things in this hobby the answer is it depends. For many (perhaps most) people Vallisneria grow like an out of control weed. For others it barely grows. And for some it just dies. In the past my Vallisneria grew very fast. Currently in the same aquarium, it is growing very slowly. I don't know why. I haven't seen a satisfactory explanation so far. It just seems to be in that mysterious category with water sprite of plants that have a reputation for being easy and yet don't grow well in certain aquariums. I have read the 'low light hypothesis' on the internet but that theory isn't consistent with what I see in local native Vallisneria americana, nor what I have observed in my own aquaria. Here is Vallisneria in the wild: In the photo above the Vallisneria is in all day completely full sunlight in a creek and grows to 6 - 8 feet in length.

    I agree with @Fish Folk anything up to 7 - 10 days is fine (possibly more depending on the species of fish). Trying to get them fed while you are not there is where the actual danger is.

    Here is a good post from @Lizzie Block showing how to upload a photo to the forum:

    Here is my current blackworm setup. It is at the sink where I hatch baby brine shrimp. I am almost out of blackworms. I am expecting another 3 lbs. on Tuesday.

    @Brandy I don't know. I think I had blackworms a couple of decades ago when I was on chlorinated water and I don't remember it hurting the blackworms. But the operative words there are 'I don't know' and 'I don't remember'.

    Java Ferns are indeed ferns. Those little sectors with pores are the reproductive part of the fern life cycle known as sporangium.

    First of all, I second everything @Koi said above. I call it mulm. In my aquariums it is a mixture decaying plant materials, fish waste, baby cherry shrimp, etc. Recently, I looked at some of it under a microscope and here is what I found.

    As @Hobbit the ammonia-nitrite conversion seems to happen a bit slower than the nitrite-nitrate. Here are some graphs from the dirted tank project showing ammonia rising first, then nitrite, finishing up with nitrate: But not all cycles are the same. This tank had soil in it higher ammonia on day 1, but once the ammonia dropped it became a more classic progression (the nitrite and ammonia dropped a couple of days after this graph): And probably the most important thing to remember with the above graphs is that all of these aquariums had healthy happy fish in them the entire time the tanks were cycling. Here a photo of the 'Dirted' tank above from November 6 (a high ammonia day). Nothing about high ammonia or nitrites gave any visible signs of distress to the angelfish and guppies in these tanks. People stress over this way too much sometimes.

    They breed every day, so you will have fry at all stages. Kind of like an assembly line that never quits. But, big fry eat little fry. Females eat eggs, males and females will eat fry. But you will always have fry at all different stages pretty much at all times. They do not come in orderly batches.

    When I see a swimming tube like that, I think caddisfly larva.

    Pretty much constantly once they get going. In aquariums they rarely live past two years. In the wild it is more like 1 year in my experience.

    They will go to where they can hide. Additional tanks are always good.🙂 They don't need a filter if you don't want to put one in.

    Looks like Elassoma fry to me. Here is some recent video of Elassoma fry eating some small invertebrate. You can even see it go down into its stomach.
  15. Daniel
    The fry are very small indeed, however I don't see a picture. Could you repost that? Soon the fry will back up in the vegetation at the top (I am assuming you have floating plants). And the parents will eat them. I have done it both ways, letting the fry remain with the parents and moving the parents and I haven't decided which way is best as I have gotten fry both ways. Currently I am doing both methods in 3 tanks to see if I can develop a preference.

    I have been eagerly following your progress on this. Would it be possible for you to post photos?
  17. Daniel
    @Cory I am having the same problem. I need to access the previous pages and so far this is impossible in Chrome, Firefox and Edge.
  18. Daniel
    @Colu can you post pictures of your UV setup? How did it work out for you?

    There really isn't any 'normal' growth rate. I have some Bacopa caroliniana that has been gently adding length and new leaves for several months. Personally, I like that rate, but other might think it was tad slow.

    I have used the iLonda because it is Alexa friendly:

    My fish seemed to think the first 3 weeks of January were a full moon. 😊

    I do what @Andy's Fish Den does. I keep them in the fridge and rinse them once a day. Alternately, I keep them in a 5 gallon bucket underneath a drippy cold faucet. Both seem to work equally as well.

    I am in North Carolina. I also have 15 open topped small aquariums and one 3 feet by 8 feet open topped large aquarium that could possibly contribute to the household humidity.🙂
  24. Daniel
    I don't keep lids on my aquariums. I have raised a lot betta and gourami fry over the years, and the standard advice has been to provide high humidity during time period between the first and second month when the labyrinth organ was developing. I have never done that and I don't think my fry have suffered from it. Calling it 'internet wisdom' wouldn't be right because I first heard it in the 1970s, but the advice is proposing a reason to explain fry loss that is more likely to due to water quality and the quality of food the fry get. Or my maybe my house is just humid. 🙂

    Soon, I hope.
