CorydorasEthan

I've never kept clown loaches before, but from what I've read, they are quite peaceful with other fish of all sizes. Just take care that all the bottom dwellers will recieve enough food! Clown loaches mainly eat worms, small crustaceans, and snails, so there is little risk that they will eat the other smaller fish that you mentioned. How many clown loaches are you planning on and what size aquarium? I hope this helps!

@Zeaqua A 40 breeder is perfect for an all Corydoras tank. Great idea! In my experience, pygmy cories will be timid at first but once they are used to the surroundings they will come out a lot more, especially when in a bigger group. It might also help to have a group of other small fish to make them feel a little more safe, and thus more active. Of course, you have to be make sure that the other fish won't eat the pygmy cory eggs - fish that come to mind would be any one of the Boraras species of rasbora (chili rasbora, least rasbora, etc.), or maybe dwarf pencilfish. I hope this helps!

Hi Tuppins, welcome to the forum! I've never actually kept silvertip tetras before, but from what I've heard, they may tend to get a little nippy, or outcompete with slower moving fish when it comes to feeding time. This Aquarium Co-Op article says something similar as well. https://www.aquariumcoop.com/blogs/aquarium/silver-tip-tetras. Nonetheless, the article also recommends dwarf gourami as a suitable tank mate. In my experience, dwarf and pearl gourami are always fairly quick to food. I've kept them with guppies, not quite as boisterous as the tetras, but something to compare to at the very least. I would say as long as you moniter the inhabitants during feeding and make sure that everyone is getting enough food, it should work out fine. I hope this helps!

I play the cello and am a fellow Bach fan! I haven't recorded any of Bach's cello suites, but I do have a performance of the first movement of Brandenburg Concerto No. 2. Albeit I am playing recorder on this one instead of cello - we had no flute player, so I had to fill in!

Welcome! Those tanks look phenomenal!

I have not, but I will check it out! Thanks for the suggestion!

Eine Alpensinfonie is a tone poem depicting a journey up a mountain, including sunrise, the forest, a waterfall, the summit, and a storm. It's one of my favorite pieces.

They look great! Paleatus cories are definitely some of my favorites!

I've never kept either of these before, but according to what I've read, both should do fine in your aquarium, as well as get along with your other fish. Your choice!

I remember playing around with this website all the time before I got an aquarium lol. I'm surprised that it says I am understocked, in the past mine's always been overstocked (I guess moving the guppies to a different tank helped!).

Um, honestly I'm not really sure. A school of them might be a little cramped in a 40 gallon. Maybe you could try going for emperor tetras instead? They are a slightly smaller than the Congos and shouldn't require as much space. Other larger tetras you could try are diamond tetras or bleeding heart tetras.

I just collect them from off the ground in my local park, let them dry for a few days, and then put them in the tank without problems. However, remember to check to make sure there are no chemicals sprayed on the trees or the ground where you collect them, because this can be dangerous for the fish. I hope this helps!

Yeah I think so. Certain species within a given lineage are more closely related to each other than with other lineages (measured by their DNA). They also share certain physical features that might set them apart from the other groups. For example, the cories in lineage 5 (C. elegans, C. napoensis, C. nanus, etc.) all have a similar coloration pattern, mouths situated slightly farther up on their heads, and tend to swim above the substrate rather than directly on it as most cories do. So yeah I would think that it would very unlikely for species of different lineages to cross. Here is a chart showing the relation between the different lineages. Here's the link to the page: https://corydoras.zone/fish/corys/corydoradinae-corydoras-lineages/ That would be a fun tank! I just bought my LFS's supply of C. hastatus (only 10 fish) during their sale. They are quite fun.

I would suggest more Corydoras. They make a tank really lively! Also you could go for a shoal of pencilfish or tetras, which would fill in the middle quite nicely. One in specific that comes to mind are Congo tetras, which get nice and big (impressive finnage and color on the males) and would stay active. I hope this helps!

Pseudomogil is a single genus, which is why some species might be able to crossbreed with one another. Species from a related genus in the subfamily Pseudomogilinae, Kiunga for example, do not hybridize with Pseudomugil species. Yes, Corydoras is the only genus in the subfamily Corydorinae currently. However, scientific studies over the group have sorted them into different lineages, which are more or less comparable to different genre (scientists are even considering renaming some lineages into new genre, like lineage 4 would become the genus Microcorydoras). Therefore, species from different lineages are unlikely to hybridize with other lineages. However, those that do share the same lineage have a higher chance of potential hybridization, so I would avoid housing them in the same tank as one another (if you do house them together monitor them closely to ensure no crossbreeding).
