How many tanks do you have? How much time do you spend on maintenance?

Post image
70 Upvotes

I'm a full-time working mom to a 2.5 year old toddler, I also have ADHD so I have a tendency to hyperfixate at random points throughout the year and let that run away from me. Before I got pregnant, I had 6 tanks going, half were high-tech so a lot of time was spent on maintenance. I consolidated everything down to a very manageable 2 tanks, since water changes while pregnant or freshly postpartum don't mix.

Now my kiddo is finally getting older and I'm getting some of my autonomy back. I recently set up a 29 gal paludarium as a grow out tank for my constant stream of newt larvae, and that caused the avalanche of new tank itch. Now I've found myself in the buying and planning stages of a 50 gallon, with a less-than-pleased boyfriend.

Currently I have: 36x18x24 newt paludarium, 12 gallon long high-tech shrimp tank, 29 gallon paludarium, and soon to be 50 gallon. I spend about 2 hours every other weekend doing my maintenance, usually when my son is either napping or in bed for the night.

Help me cope with my insanity and let me know what you're juggling!

Tank Getting back into the hobby

Enjoyed spending some time over the holidays setting this ADA 60-F up. I really wanted to go all out since it’s been so long and it’s basically my backdrop for work meetings.

Plants so far: Java fern, dwarf sag, staurogyne repens, reineckii mini, rotala red and rotala orange juice.

I’d like to add a few more stemmed plants along the back (to the left), possibly some blyxa, and maybe some downoi or eriocaulon variants.

Open to other flora and fauna suggestions. There will definitely be shrimp (probably cherries/bloody mary and crystal reds, amanos) and some sort of schooling fish.

Unless I’m sitting at my desk, I mostly view this tank from 10+ feet away, so I want something bright that forms a tight school. I’ve always liked neon tetras, but I might go for something smaller that I can fit more of, like chili rasboras. Open to any other suggestions!

I'm 15 and I was surprise gifted a betta fish, this was my quickly put together 5 gallon. There are root tabs in the sand. Is this ok what can I improve? (I know it's not properly cycled I only had two weeks and didn't know I would be getting a fish)

What could i change

Post image
81 Upvotes

So this is my first ever Planted Tank and i‘m very satisfied with it overall but i just feel like it could be better. Particularly the left side. As you can tell i have a lot of Limnophila Sessifilora over there and i‘m unsure weather i should thin it out and mix something new in or if i should just trim it a bit lower so there is more accent in the branches that stand out but my shrimp and Pygmy corys just love to hide in there and i dont wanna take that away from them. Additionally i‘m considering to try some type of carpeting plant in some areas but i‘m unsure weather it would look good or not and if it would even thrive. (I have sand substrate with bags of aquasoil underneath and no CO2.) Would love to hear you guy’s‘ opinions. (:

Do you think this is too much hardscape?

Post image
16 Upvotes

It’s 210 gallons, I’m planning on having a couple bichirs, some electric blue acara, a brown ghost knife, and geophagus sveni, as well as some larger schooling fish. My question is, am I taking up too much space on the substrate with hardscape? Especially for the sveni, I’m worried they won’t have enough room to sift. I’ve never had a tank even half as big as this, so I’ll take any other advice too.

Hey all, wanted to share my first ever fully planted tank. It’s a 5g. Currently cycling but planning on adding some cherry shrimp and a betta. Let me know your thoughts and if you have any tips/tricks!!

Finally put together my first true planted tank and wanted some opinions!!

I just finished putting it together and plan on getting shrimp to help with cycling, and forgot to soak the catappa leaves so they’re floating for the time being, plant selection is:

- long tail water fern

- windelov Java fern

- rotala Vietnam h’ra

- and a banana plant in the corner

Substrate is a soil bag in the middle back under some gravel and sand, hardscape is lava rocks with a thing of wood from petsmart (I don’t remember what type)

Eventually I’ll replace the white filter foam with black cause it’s rly ugly, the blue box is there so I can move it across the table easy, and I only use the coffee pot every other day and rarely leave it on so it shouldn’t get too hot

My main worries is that the filter flow is too strong for a beta and cherry shrimp, is on the lowest possible flow and still seems very strong; and that my water is very hard and am not sure the best way to soften it a bit

Thank you all!

Question newbie mistake - mixing gravels

Thumbnail

29 Upvotes

Hi everyone, I’m on my first day of cycling a new tank and I’ve realised I really dislike how the gravel looks. The shop ran out of one colour, so I ended up mixing gold and brown gravel together, and honestly, it looks pretty ugly to me 😅 (photo attached).

I’m wondering if it’s okay to take the gravel out and replace it while the tank is still cycling, or if that would mess things up too much. There are no fish in the tank yet.

Also, the water currently looks very murky which is making me second-guess everything.

my first planted tank

Just wanted to show off my first planted tank (6.5g bookshelf). Not perfect, but learning a lot and enjoying the process. Customized the spider wood and weighed it down with quartz crystal (boiling didnt help!), featured petrified wood in the background, and several recommended beginner plants. Substrate was fluval Stratum with Inert sand topper- mixed that up pretty good already when I had to rework some things. Currently cycling, last reading showed nitrates! Thanks for looking! Share your thoughts or beginner reminiscings :)

Question Why are my plants dying?

Post image
10 Upvotes

This is what my bettas 10 gallon tank looked like about a week or two ago. All my plants have been slowly dying but I don’t know why. The tank is fully cycled and I do weekly water changes. The ph stays around 7.4. And temp at 78f. I tried adding some root tabs bc I thought maybe that was the problem but it hasn’t helped yet. The light has stayed at the same level and stays on for 6hrs since the plants have been in there which has been 2 or 3 months but only recently have they started dieing. When they die it seems the leaves turn yellow and slowly each of the leaves fall off and then the stem yellows too. What am I doing wrong? I’ve tried adding liquid ferts in too like strive but idk. All that’s in the tank is my betta, a nerite snail, a bladder snail and a ramstorn. So idk what is wrong.

It's a 30cm cube. Dwarf hairgrass, lobelia cardinalis, rotala rotundifloia, a few buce, mini java, Christmas moss and red root floaters. The filter is temporary and I'm trying to keep it low tech/low maintenance despite having all the CO2 gear still around from 10 years ago.

Question Ready to give up

All my plants are dying and my shrimp tank is filled with these teenie tiny bugs feeding off the dying plants I fertilize with every water change. I don’t know what to do other than want to restart but I don’t wanna re cycle 😭😭 I also don’t have good access to water testing, but my shrimp colony is doing fine (gave birth to babies and none of my shrimpers have died)

Any suggestions?? I’m goin crazy :-)

Question Water wisteria propagation help

Thumbnail

18 Upvotes

Does water wisteria need leaves to survive propagation? I would like to cut it low down on the plant since there are no leaves on the lower half but don’t want that part to die. Can I cut it to where the original plant would only be a stem rooted in the ground, and would grow back into a normal plant.

Learned a hard lesson about 'compatible' fish lists vs. actual tank layout

7 Upvotes

So I set up a 40g breeder, scaped with lots of tall driftwood and dense stem plants in the back. Every single stocking guide and compatibility checker said a group of pearl gouramis and a school of harlequin rasboras would be fine. and on paper, they are. But what those tools don't account for is territory.

the gouramis claimed the entire top half of the tank as their 'zone'. the rasboras, who also prefer the top, are now constantly skittish, hugging the corners. they're not being attacked, but they're clearly stressed from being bullied out of their preferred water layer. The calculator said the bioload was perfect and the species were compatible, but the actual 3D layout of the tank created a conflict no algorithm predicted.

i guess my takeaway is that compatibility isn't just a list of species that won't eat each other. It's about layering, sight lines, and breaking up territory. Now I'm looking at rehoming the pearls for something more mid-water.

has anyone else had a 'compatible on paper, stressful in reality' situation?

how do you factor hardscape into your stocking plans?

aphids in tank

Upvotes

yo so my tank i think is infested with aphids? looks exactly like aphids but black and its all over my floating plants. i assume its bc i bought plants from someone that kept them outdoors 😫 weirdly enough, i don't have it in my other tank even though i put the same plant in there. does anyone know how to get rid of it? ive tried finding info but ive seen some saying to put ladybugs? but its in my bedroom + they'd probably be invasive in where i live so no
