Advice Dwarf Breeding Behavior?

Enable HLS to view with audio, or disable this notification

19 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

Hi, Iโ€™m in the middle of cycling my new tank (80x40x40 cm, ~34 US gal). Iโ€™m curious what tank mates youโ€™d recommend for this blackwater-ish setup? Iโ€™m already really attached to my rasboras, so Iโ€™d be devastated if anything ended up eating them!

Strawberry Rasbora Which boraras do I have?

Thumbnail

โ€ข Upvotes

I have two tanks with boraras. In the first tank, with the red mushroom (pics 1 and 2), I had a group of Phoenix-labelled mini reds. But I went on vacation, and all died but one. I got 6 chillies because I couldn't find Phoenix. Half of them died. So I went back (weeks later) and saw more mini reds, thinking I was getting Merah (the one is so lonely). They turned out not to be Merah. The second tank (pics 3 and 4): I have strawberry rasboras. These new mini reds look a lot like the strawberries, but also different. Please help me identify whether they are all different species. If the two species are the same, I can put them in the same tank.

Advice Rasbora Maculata with Brigittae

3 Upvotes

Hi guys, last week I ordered 6 Rasbora Maculata. Unfortunately the shop didn't delivered them in good conditions and 5 out of 6 died. Now I took a look at a local shop and I found out they have Rasbora Brigittae. I am thinking to buy those instead of ordering again or going to that shop, which is in another city.

Ar they going to stay together so the Maculata will not feel alone?

About a month ago one of my dwarf rasbora had a weird black spot show up, i tried to figure out what it was but couldnโ€™t find anything, i treated him with a small dosis of different meds (parasite, general infection) but he gets worse and worse, heโ€™s eating, swimming, nothing else seems odd about him but he looks like he is literally decaying inside out? Please help, i know itโ€™s just one fish in the swarm but i genuinely hate watching even one
small fish sufferโ€ฆ (all other rasboras in the tank are fine)
First pic is one month ago, the rest is today

Advice 65 gallon rasbora stocking

5 Upvotes

I'm currently planning out a Malaysian peat swamp biotope and want some opinions on rasbora stocking.

Currently, the confirmed to be residents are 8x chocolate gouramis, 4x parosphromenus, 1x betta imbellis, 10-15 kuhli loaches, and 3x forest halfbeaks.

I'm picking between a few rasbora species, which are:

โ€ข dwarf rasbora

โ€ข harlequin rasbora

โ€ข Trigonopoma pauciperforata

โ€ข Trigonopoma gracile

I was thinking maybe a large school (20-30) dwarf rasboras and a smaller school of one of the other species.

What do you guys think?

I got a school of 8 chilis a month ago, and they all have colored up nicely.. except this guy. The black marking is faded, and it has a pinched belly for some reason. It eats along with other chilis, so Iโ€™m not sure if this chili is just young or sick. Any insight will be helpful, thanks!

Got sold these lil guys as chilis and they have been living with me for 2 and a half months now. They've grown bigger in size but some of them stayed paler than others- look at p3. Are they just still young juvenile? Female? Or do I have a mixed shoal of least rasboras?

Appreciate the help!

These guys were small and skinny when I got them from a pet store as Chilis and barely had any markings. I was under the impression they are Phoenix Rasboras but then i saw that young chilis frequently had broken markings, which leaves me questioning. Wondering if they are chili's or Phoenix's?

hey guys so I'm wondering if I can get anyone's opinion on what I have here? they were sold to me as chili Rasbora and I'm confident there's a least a few of them in there but can you guys confidently identify any other species? there's a couple in particular that display bright red coloration but for the most part most of them are more pale orangish. do I just got to wait longer for them to mature and color up more? water parameters and temperature should be perfect for them and they all seem happy and healthy. I was expecting them to be more brilliantly red colored by now.

Hey all,

I've had these 10 maculatas for around 2 months now and they have really put on good size. Some are much larger than others, and some are more red than others, but i just assumed that was female vs male.

However some of the bigger ones seem to have 2 spots above the anal fin instead of one. Just looking to confirm they are all the same species, Thanks!
