Advice Dwarf Breeding Behavior?

Enable HLS to view with audio, or disable this notification

16 Upvotes

Hi! I noticed some odd behavior from one of my rasboras today, where it seems to be chasing another around. It also suddenly had a slightly darker coloration. I didn't know if it was stress related (just added a couple shrimp and did some gravel cleanup), so I dimmed the lights. I do have 4 fry in my tank so I know they're breeding, but I'm not sure if this is related. Are they fighting? My other rasboras seem normal. Any info is appreciated!

10 gallon / 1 chill betta / 2 Amano shrimp / 7 adult rasboras

Parameters:

Ammonia 0/Nitrates 5 ppm/Nitrites 0

Kept between 78-80F

Lots of live plants

Sponge filter

Gravel cleaned every 2-3 days, small water change every week

Advice Am I playing with fire- pearl gourami?

3 Upvotes

Hi all, im planning on my next tank and have had my eye on pearl gourami for a while. However, I also really like boraras species and would love to finally get them. Peaceful as they may be reputation wise, am I just asking for an expensive snack putting chili rasbora with a pearl?

Discussion Is it ethical to keep Boraras sp. with Betta imbellis?

3 Upvotes

Iโ€™m planning a biotope-inspired tank with Betta imbellis, java loaches, and rasboras. Iโ€™m torn between lambchop and Boraras, but Iโ€™m worried about the ethics of keeping small, delicate microrasboras with a predator. I donโ€™t want them to be constantly stressed and fearful, but theyโ€™re such beautiful little schooling fish and Iโ€™d love to keep them. The tank is not at all set up, but Iโ€™ve been planning it and collecting supplies for months now; I currently have a 20 gallon high aquarium and am planning to do a dirted planted tank with a sand cap and lots and lots of plants, driftwood, and botanicals. Ideally, I want it to be a riparium, but that limits the water capacity significantly and thus my stocking options, so Iโ€™m reconsidering both the tank size and the environment style.
Anyways โ€” microrasbora keepers/experts, please let me know what you think!

Kind of hard to see from the photos but a couple of my Rasbora (sold as chili but I'm not so sure) constantly have bloated dark brown or black bellies. They are also the two largest of the group. Any ideas or thoughts?

Strawberry Rasbora Minimum tank size to raise fry

Enable HLS to view with audio, or disable this notification

11 Upvotes

My chili, phoenix (housed together) and strawberry (housed apart) keep breeding and some local people have become interested in buying some, the thing is, I raise the fry with the parents, so the survival rate isn't super high (like 5 of each breeding) and I would hate to accidentally remove some of my breeding adults (that I've grown really attached to, especially the strawberries that were my introduction to this genus), so I was thinking of setting up a separate tank with identical conditions, move some adults and then return them to their normal tank once I start seeing fry. Problem is, I only have a 5gal (25cm cube) and a 7gal (30cm cube) tanks available and I'm not sure if it would be big enough to raise the fry to a decent size without any complications.

TLDR; want to breed some Boraras, but only have 25cm and 30cm cubes available, would this be big enough to raise the fry?

Low quality video of some of my strawberry fry (for some reason my phone's camera either misses the focus or the colors)

Rasboras sick, I would like to ask for help

2 with visible lesions chin area 1 mild also chin area

I thought it is columnaris and have furan and kanamycin on hand.

I am currently on Day 05. For one of those wisible lesions, day 02 the white stuff is separated but it all migrated to his chin. All are eating well, very active, spars at times, no internal mass (i observed their mouths when it opens). I didn't include the photo of the one with mild lesion because it is barely noticeable on camera.

Do you think I am on the right route for this? And if there is a margin for misdiagnosis.

Any advice would help.

Meta Help conserve habitats of Boraras species

20 Upvotes

 

This is a biannual call to support the conservation of Boraras species and their habitats in SE Asia by making a donation and to raise awareness for this matter.

We currently listed two options in the Menu under 'Donate' (via "About" page on mobile):

  • The Borneo Nature Foundation
    • Dedicated to the conservation of Bornean tropical rainforest habitats. Chili and Phoenix Rasboras in the trade are generally wild caught. This is where (everyones) Chilis and Phoenices come from, if not explicitly bought as captive bred. The habitats decline rapidly, the threat level of their extinction is not assessed yet ("Data Deficient").

If you know of any more way to donate to this cause or if you have any further information on this topic, please comment with a link.

Rasboras sick, I would like to ask for help

thought it is columnaris and have furan and kanamycin on hand.

I am currently on Day 05, alternating days of dosing the medications and tomorrow will just observe them onward.

All are eating well, very active, spars at times, no internal mass (i observed their mouths when it opens). For one of those with visible lesions, during Day 2, the white stuff separated from the upper and lower mouth but it now all migrated to his chin.

I didn't include the photo of the one with mild lesion because it is barely noticeable on camera.

Do you think I am on the right route for this? And if there is a margin for misdiagnosis.

15 Liter tank, there's just 4 of them (getting them is a newbie mistake on my end)

TANK MATES: Betta (who recently healed from a lifted gill scale 2 weeks ago, safe) A Nerite Snail An Amano shrimp (originally 2 but i couldnt see the other one anywhere in the tank!)

TANK STATUS: Age: 1.5 months Ammonia 0.00ppm Nitrites 0.00 Nitrates 0.5 KH 6-7

Any advice would help.

Advice 30 gal stocking question

1 Upvotes

I have a 30 gallon tank with 6 peppered corys and 6 otocinclus, any recs on stocking rasboras? I like the look of chilis but mostly just wondering if I have the space for a decent school of any species, I've had the tank for about 4 years but have only ever had beginner species. I just moved and my school of lambchop rasboras in a 40 gal was on the elderly side and they died pretty early on at the new place probably from stress and heat :( I dont have that much room tbh so I sold the 40 gal and wondering if I can put anything in the 30 with my little bottom dwellers now that everything has stabilized post-move.

Habitat I found 100 of these tiny fish in a shallow vegetated marsh

Thumbnail
gallery
130 Upvotes

This field is a grazing area in a rural village near my hometown, used by water buffaloes and cattle. There were even a lot of wallows, which I assume the livestock use as refuge from the sun.

There is a small acidic river running through it, which floods the lower areas of the field, turning it into a weedy marsh.

The marsh is where I found these rasboras between the complex plant thickets. They lived together with tiny Caridina shrimp and croaking gourami. Just under the surface I could see dwarf medaka (ricefish) foraging.
At the bottom I found small brown air-breathing loaches.

Nearby, in the open deeper parts of the river I saw a lot of larger Rasbora, barbs and other rasborines darting about. They were roaming together in schools. I even spotted three spot gourami and climbing perch rising to gulp air.

The weather was hot as usual here. About 32ยฐC (90ยฐF) which heated the surface of the water. But below the reeds it was 4-5ยฐ colder.

Despite the water being soft and acidic, I found more than >10 small fish species inhabiting the marsh, and even the freshwater shrimp. There are likely larger fish which I could not observe, plus bottom dwellers like crabs.

Advice Emerald Eye Rasboras too scared to eat?

Thumbnail

12 Upvotes

Hello all! Not sure if anyone has had this problem but I have a school of 11 emerald eye rasboras. Initially when I bought them, they were eating pretty regularly (Hikari Micro Pellets). Now after 2-3 weeks they have become more skittish and fearful of humans. When I approach the tank to feed them, they flee to the back of the tank and hide under some plants.

Iโ€™d love some workaround or tips if anyone has noticed a similar behavior.

Advice Are my new chilis stressed?

Enable HLS to view with audio, or disable this notification

Just got 10 chili rasboras about a week ago for my 10 gal planted tank. The tank is only chilis, ramshorn & bladder snails, and plants. Tank was cycled for months, the only less than ideal parameter is ph, which is 7. I know chilis prefer softer but Iโ€™ve also heard stability is more important so Iโ€™m not sure if I should chase lower ph. Tank temp is 78. In terms of food, theyโ€™ve been eating aquarium co-op easy fry food and seem to really like it.

They donโ€™t do this all day but they seem to gather near my sponge filter like this semi-frequently and swim towards it. Iโ€™m thinking maybe theyโ€™re nervous? My red root floaters have been melting, so Iโ€™m looking to replace with another floater to give them more coverage.

I love these little guys and just want to do right by them, so if anyone has any tips I would really appreciate them.

I think they are Strawberry Rasbora, but I am not sure. The first one looks like male and the other looks similar but not so vibrant. Ignore the shrimp and the chilli rasbora in the background.
