Hi three so I’m new into this hobby and set up a “attempted” planted 5 gallon tank. It so far has been going okay, but most of plants keep dying, so I’ve been replacing them bi monthly, this might not be related but wanted to add it just in case. While my bettas behavior has not changed drastically it has been resting a lot more, and I’ve noticed a color change, and also his fins seem to be slowly dwindling down. I’m worried he might have fin rot! Does anyone know if he does, and what I can do to help? It also might be the strong filter pushing him around, he does often flail against the current. Thank you!
Possible fin rot and other problems! (Betta fish)

I can't see all the plants properly but I would guess some of them are garden plants and will rot when kept underwater.
AQUARIUM PLANTS 1.01
LIGHTING TIMES
Most aquarium plants like a bit of light and if you only have the light on for a couple of hours a day, they struggle. If the light doesn't have a high enough wattage they also struggle. Try having the tank lights on for 10-12 hours a day.
If you get lots of green algae then reduce the light by an hour a day and monitor the algae over the next 2 weeks.
If you don't get any green algae on the glass then increase the lighting period by an hour and monitor it.
If you get a small amount of algae then the lighting time is about right.
Some plants will close their leaves up when they have had sufficient light. Ambulia, Hygrophilas and a few others close their top set of leaves first, then the next set and so on down the stem. When you see this happening, wait an hour after the leaves have closed up against the stem and then turn lights off.
--------------------
TURNING LIGHTS ON AND OFF
Stress from tank lights coming on when the room is dark can be an issue. Fish don't have eyelids and don't tolerate going from complete dark to bright light (or vice versa) instantly.
In the morning open the curtains or turn the room light on at least 30 minutes (or more) before turning the tank light on. This will reduce the stress on the fish and they won't go from a dark tank to a bright tank instantly.
At night turn the room light on and then turn the tank light off. Wait at least 30 minutes (or more) before turning the room light out. This allows the fish to settle down for the night instead of going from a brightly lit tank to complete darkness instantly.
Try to have the lights on at the same time each day. Use a timer if possible.
--------------------
LIST OF PLANTS TO TRY
Some good plants to try include Ambulia, Hygrophila polysperma, H. ruba/ rubra, Elodia (during summer, but don't buy it in winter because it falls apart), Hydrilla, common Amazon sword plant, narrow or twisted/ spiral Vallis, Water Sprite (Ceratopteris thalictroides/ cornuta).
The Water Sprite normally floats on the surface but can also be planted in the substrate. The other plants should be planted in the gravel.
Ambulia, H. polysperma, Elodia/ Hydrilla and Vallis are tall plants that do well along the back. Rotala macranda is a medium/ tallish red plant that usually does well.
H. ruba/ rubra is a medium height plant that looks good on the sides of the tank.
Cryptocorynes are small/ medium plants that are taller than pygmy chain swords but shorter than H. rubra. They also come in a range of colours, mostly different shades of green, brown or purplish red. Crypts are not the easiest plant to grow but can do well if they are healthy to begin with and are not disturbed after planting in the tank.
Most Amazon sword plants can get pretty big and are usually kept in the middle of the tank as a show piece. There is an Ozelot sword plant that has brown spots on green leaves, and a red ruffle sword plant (name may vary depending on where you live) with deep red leaves.
There is a pygmy chain sword plant that is small and does well in the front of the tank.
--------------------
TRUE AQUATIC VS MARSH/ TERRESTRIAL PLANTS
Lots of plants are sold as aquarium plants and most are marsh plants that do really well when their roots are in water and the rest of the plant is above water. Some marsh plants will do well underwater too.
Hair grass is not a true aquatic plant, neither is Anubias.
Some common marsh plants include Amazon sword plants, Cryptocorynes, Hygrophila sp, Rotala sp, Ludwigia sp, Bacopa sp. These plant do reasonably well underwater.
True aquatic plants include Ambulia, Cabomba, Hornwort, Elodia, Hydrilla and Vallis.
The main difference between marsh plants and true aquatic plants is the stem. True aquatics have a soft flexible stem with air bubbles in it. These bubbles help the plant float and remain buoyant in the water column.
Marsh plants have a rigid stem and these plants can remain standing upright when removed from water. Whereas true aquatic plants will fall over/ collapse when removed from water.
--------------------
IRON BASED PLANT FERTILISER
If you add an iron based aquarium plant fertiliser, it will help most aquarium plants do well. The liquid iron based aquarium plant fertilisers tend to be better than the tablet forms, although you can push the tablets under the roots of plants and that works well.
You use an iron (Fe) test kit to monitor iron levels and keep them at 1mg/l (1ppm).
I used Sera Florena liquid plant fertiliser but there are other brands too.
--------------------
CARBON DIOXIDE (CO2)
There is no point adding carbon dioxide (CO2) until you have the lights and nutrients worked out. Even then you don't need CO2 unless the tank is full of plants and only has a few small fish in.
There is plenty of CO2 in the average aquarium and it is produced by the fish and filter bacteria all day, every day. The plants also release CO2 at night when it is dark. And more CO2 gets into the tank from the atmosphere.
Don't use liquid CO2 supplements because they are made from toxic substances that harm fish, shrimp and snails.

Onto the fish. The tail might be rotting but it looks like bites. Sometimes male Bettas bite their tails when stressed and it can lead to infection. It might be fin rot too.
Check the ammonia, nitrite, nitrate and ph of the tank water.
Do a 75% water change and gravel clean the substrate every day for a week.
Make sure any new water is free of chlorine/ chloramine before it's added to the tank.
See how it goes over the next week. if it gets worse, post more pictures and maybe add some salt.
-------------------
SALT
You can add rock salt (often sold as aquarium salt) or swimming pool salt to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water. If there is no improvement after 48 hours you can double that dose rate so there is 2 heaped tablespoons of salt per 20 litres.
Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, Bettas & gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.
The salt will not affect the beneficial filter bacteria, fish, plants, shrimp or snails.
After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.
If you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.
When you first add salt, add the salt to a small bucket of tank water and dissolve the salt. Then slowly pour the salt water into the tank near the filter outlet. Add the salt over a couple of minutes.

Thank you! So I have been definitely turning the lights directly on and off, so I will definitely start trying to ease them off and on. As for the plants, I definitely do have quite a few marsh ones. For the most part I get all my plants at petco, which I’m not realizing that might not be a good idea. Any recommendations for online plant stores? As for the fish, I will do the water change, is there a possibly the filter might be stressing him out too? It’s rather strong and pushes him around. Thank you
If the filter blows the fish around the tank then it is probably too strong for a Betta. You can try changing the angle of the filter outlet so it blows into a rock or a corner of the tank rather than across the length of the tank. Depending on the actual filter, some let you reduce the flow but you would have to check the instruction booklet.
