    Bristlenose & clown loaches killing/eating corydoras?

    Also, The filter & pump are in a sump under the tank. The water collects via an overflow filter chamber, drips then rises through three types of filter medium, then gets sucked up through a pump and back into the tank. I clean the first filter media (white spongy filter) at every water...

    Bristlenose & clown loaches killing/eating corydoras?

    Thanks Colin. I'll take photos tomorrow when the lights are on again. The new fish (which admittedly I bought all at the same time) were 5 peppered cory catfish, 2 blond bristlenose and 2 clown loaches. The existing fish prior were 5 julii cory catfish, 5 black bristlenose, 1 clown loach, 1...

    Bristlenose & clown loaches killing/eating corydoras?

    Hi Byron! It's a 200L tank. At the moment I have four livebearers, seven young bristlenose catfish, three clown loaches, and it looks like only two remaining corydoras catfish. Since the new fish were introduced, it's only the corys that have suddenly been dying, including the juliis that...

    Bristlenose & clown loaches killing/eating corydoras?

    Hello! I've had 5 Julii corydora cat fish for at least a year in my tank, as well as livebearers. Over time I've also brought in some bristlenose catfish and a clown loach. More recently I introduced 5 peppered cory catfish, a couple of extra bristlenose catfish and 2 more clown fish. Since...

    What's the big fuss with guppies and breeding true?

    You've got me thinking now. When I bought my guppies, there were a few little boys with yellow and orange that looked rather Endler-like to me. I asked the LFS person if it was possible that they were interbred, but he said something about them being a particular type of guppy. I didn't think he...

    Endler fry survivability in a heavily planted community tank

    Hi! I'm new to this too, but I've noticed that my guppy fry tend to swim up really high in the tank most of the time, and only sometimes venture down through the mid-height section. They tend to stay where the plants are. I've got elodea & blue stricta through the back of the tank, and that's...

    Holiday feeding, guppy fry & catfish

    Thanks EA. I have no idea why the female guppy died. They all looked active when we arrived home, but she was dead by the next morning. So strange. She was very pregnant; perhaps something went wrong with that? The others all look active and fine. I can't see anything sluggish or off-colour...

    Holiday feeding, guppy fry & catfish

    FYI: After twelve days away, I returned and found all the fish swimming happily, except for one male who had completely disappeared. This has happened before; fish can get sucked into the overflow chamber (he wasn't in there) and, if they're very unlucky, into the plumbing that leads to the...

    Holiday feeding, guppy fry & catfish

    Thank you, Byron. Thank you, Byron. It's autumn here, and a sunny day today, so it was easy to find some fallen, dry leaves that I've popped in the tank. I didn't have time to dry them further, and I wasn't sure how many to put in or how soon they'd be worthwhile for the fish. So, although I...

    Holiday feeding, guppy fry & catfish

    Thank you, Byron! I didn't know that. The guppies always seem so hungry, and I worry about underfeeding them if there are fry in the tank (worry that they'll seek out the fry to eat, in their hunger). I'm still working out the volumes to feed them. If I put in one 'pinch' of flake food, it's...

    Aragonite, Coral Sand, Raised pH, KH, GH

    Thanks Jen! It looked like a jungle until I trimmed that elodea & took the hairgrass out this afternoon. I hope the fishies don't get all stressed with the extra open white spaces now. It is a little reassuring for me being able to actually see everywhere in there now, but I worry about the...

    Holiday feeding, guppy fry & catfish

    Oh! My water parameters from last night, which was five days after a 70L water change: Temp 26C pH 7.8* Ammonia 0 Nitrite 0 Nitrate 10ppm** KH 6dH GH 11dH *pH is, I believe, somewhere between 7.6 & 7.8. It's always constant, whatever it is ** Nitrate orange colours were hard to read, but it...

    Holiday feeding, guppy fry & catfish

    Hello all. I haven't been in here much in the past few weeks. In that time I've bought some guppies (M & F) and julii cory catfish for my 220L planted tank. In a few days I'll be going away for 10 days. I've bought some Vitalis brand '7 day freshwater holiday grazers'. I'm meant to stick them...

    Aragonite, Coral Sand, Raised pH, KH, GH

    I need a better camera, but here is my tank. Today I took out the hairgrass, as it turned brown no matter where it was in the tank. I trimmed back a lot of the elodea, and replanted the cut stems where the hairgrass used to be. I can see much more in there now, but I'm afraid I've taken away...

    Aragonite, Coral Sand, Raised pH, KH, GH

    Aw. Thanks Jen. I'm feeling very guilty, for having bought fish sooner than I intended, and more than I intended, and females when I wasn't going to. I did see your post a few days ago about your recent discovery about your water. I'll have to go back to catch up. How's it panning out? I...

    Aragonite, Coral Sand, Raised pH, KH, GH

    Oh, and some of the fish started intermittently 'flashing', and my smallest boy had slightly clamped fins for a couple of days but now doesn't, but now my smallest girl has very clamped fins. Her tail comes to a point now. The LFS said they're the first signs of white spot (is that the same...

    Aragonite, Coral Sand, Raised pH, KH, GH

    FYI I decided to go with guppies & julii corydoras. I let myself be talked into getting both M & F guppies from the LFS. This was not my intention, and I shouldn't be so impulsive with such things. However, they assured me that they would accept donations of any fish I breed if I can't keep them...

    Aragonite, Coral Sand, Raised pH, KH, GH

    Thank you Steven. I decided not to play with things further. I still haven't invested in a Hanna Industries pH checker yet, so I'm not entirely confident that I actually know what the precise pH of my tank water is, but I am confident that it is constant. No matter what the GH or KH or anything...

    Aragonite, Coral Sand, Raised pH, KH, GH

    Thank you, Steven. I worked out that if I add the recommended amount to change the volume of water being added from the existing ~3dH GH (my tap water) up to the desired GH, that works. The KH takes longer to hit the desired amount (overnight, then it stays fairly stable, with a very slow rise...
