This morning as I was getting ready to feed my betta and minnows I noticed my betta wasn't the first one at the surface waiting for food. Ended up finding her just behind the aquarium on the table, gentle scooped her up and was able to get her into the water rather quickly. She couldn't have been out for long considering I saw her just before I took the lid off the tank. By the time I turned around with the food I noticed her, so maybe a minute at max? She still felt wet when I picked her up so that's luckily at the very least. She immediately sank to the bottom after the fact hiding in a corner of the tank. She was breathing deeply and swimming in an odd way when she did move. A minute or two later she was able to dart to the surface for air and after that started swimming more or less like normal even coming to the surface to eat and acting normal.
Really my big thing here is just wanting some advice. What should I be looking out for or doing as a precaution? She looked fine minus some small tears in her fins and what appeared to be lost scales left where she landed. She already has what I think may or may not be fin rot(I have medication on the way from the co-op) so I will have that at my disposal.
I am really just looking for some sort of advice, i know she wasn't out for long but I'm just trying to be careful. What should I be looking out for and what precautions should I take? Any advice id appreciated, I have additional info on my tank below.
Tank size: 10 gallon (top fin starter set)
pH: 7.8~
ammonia: 0ppm
nitrite: 10ppm
nitrate: 25-30 ppm
kH: N/A
gH: N/A
tank temp: 76-78 degrees F
Fish Symptoms (include full description including lesion, color, location, fish behavior): White coloring on the tip of her "main" fin (it was torn on a decoration, now removed), smaller holes that are new from the fall and probably a few lost scales
Volume and Frequency of water changes: Once every week and a half to 2 weeks
Chemical Additives or Media in your tank: Seachem stability when adding new fish and tetra or prime for conditioner. Media consists of the 10 gallon HOB filter, the cartridge it came with and the blue bacteria grid. Plus a sponge filter on the other end of the tank for aeration and extra filtration. Plus I have some java ferns that have been in the for awhile.
Tank inhabitants: betta (splendens) female. 5 white cloud minnows (3 male, 2 female), two java ferns, a dwarf aquarium Lilly, a water sprite and some moss balls.
Recent additions to your tank (living or decoration): minnows we gotten 2 weeks ago along with the sprite. Lilly was added just before new years(sprouting fine so far)
Exposure to chemicals: I use easy green and plan to add root tabs soon for the Lilly.
Sorry if this is long, just wanted to offer as much info as I can.
