Betta dead!!!

[mrseigel]

Hi all,
Unfortunately I now believe I introduced an internal bacterial infection into my display tank from the fish I had shipped to me. I'm new to the hobby and didn't quarantine my shipped fish but for a few days. So far, 7 of my neon green rasboras have died. I now quarantined the remaining 5 and began medicating the water column with Kanaplex. They kept dying and then I started mixing with Focus and administering via food. Since then none have died. However, I woke up this morning to my dead betta in the display tank. I now want to medicate the display tank (10 rummy nose rasboras, 6 albino corys) but have mystery snails (and babies). My question is can I administer Kanaplex and Focus through food and just block my snails from eating it? Would that be safe? Also, I have tested multiple times and all my water parameters look good.

Are you able to describe the symptoms that the fish show before dying? It might help others offer advice.

From what I can find online Kanaplex is not compatible with snails, not sure if you can move them elsewhere? However if you're still losing fish after dosing the Kanaplex may not be the answer, hard to say without knowing the symptoms.

I believe it is hemorrhagic septicemia because my neons would develop red streaks of blood near their fin and would start swimming awkwardly and deteriorate very quickly and die within 24 hours.

Do you have any photos?

Have you noticed any other symptoms before they die? You've tested your water and you say that's fine but unfortunately it can only tell us that there's no ammonia, no nitrite and hopefully Nitrates are as close to zero as you can manage. It doesn't tell us if there a contaminant or bacteria etc...so the first thing we do when we notice something off (and especially when we find dead fish) is a massive water change to reduce or dilute whatever the bad thing is

The blood streaks are pretty conclusive, but with lab tests (I'm sure we're all mad scientists somehow) we can't know exactly which antibiotic to use. Plus a lot of us live where a medical prescription is needed for any antibiotic. I haven't used any for fish for 25 years.

My concern would be the cause of death in the second tank, the Betta, and if it is a coincidence.

Here are photo of one of the rasboras that died and the betta 1 day before it died. You can see the red blood streak above its fin in the rasbora. Sometimes they will aslo swim upside down right before they die. I've bee. Doing ~30% water changes every other day.
