So I was just watching my fish tank as one does, and I noticed that a fry I've had for roughly 6 months (born in my tank) was suddenly really skinny, unlike her normal plump appearance.
I did some research, and I'm thinking it may be internal parasites, but some help or feedback would be nice.
1~What type of fish is afflicted? In addition, please describe what is wrong with the fish to the best of your ability (i.e. cotton like growth, bloated, etc.).
A young silver-and-black female platy, she suddenly lost basically all of her weight/size and her fecal waste looks abnormal.
2~What are your tank parameters (ammonia, nitrites, nitrates, temp, pH)? Please give exact values.
I'm unsure, since my liquid test kit is outdated and the test strips I have are old and bad. Hoping to get a new liquid test kit soon.
3~How large is the tank? How long has the tank been set up?
10 gallons, about a year and a half.
4~What type of filtration are you using? Please give the name and number (i.e. Fluval 304) and amount of gph if known.
Top Fin Small Silenstream PF-S, gph
5~How many fish are in the tank? What kinds of fish are they and what are their current sizes?
About 11 fish; 8 platies (not including affected fish) [3 adults, 5 fry], one small bristlenose pleco, one medium cory catfish, along with two mystery snails and possibly one small ghost shrimp.
6~When is the last time you did a water change and vacuum the gravel? How often do you do this? How much water do you remove at a time?
Last water change was a couple weeks ago, haven't vacuumed in a bit. I don't do water changes too often due to other plans and an unfortunately huge lack of motivation, and vacuuming is a rare event.
7~How long have you had the fish? If the fish is new, how did you acclimate it/them?
She's been around for roughly 6-7 months and was born in my tank.
8~Have you added anything new to the tank--decor, new dechlorinator, new substrate, etc.?
A couple new small plants, yes.
9~What kind of food have you been feeding your fish, have you changed their diet recently?
Nutrafin flakes and discs, no recent diet change. They're also fed flakes every 3 days and discs every 2 days.
Pictures of the fish will be posted tomorrow/the day after this was posted due to phone limitations, my apologies.
